First of all, GREAT job on 13 days. Second of all, yes, I too felt depressed, actually for months after I quit and went into recovery. Key here is, recovery. Are you able to get to meetings, do you have a support group? Super important, as I would obsess on the money lost, etc., and at times, I still do, but, for me, being in recovery was key. Although you do seem as though the financial drain has been hard, and I get it, the worst case scenario, of going back, to gambling, or even suicide, hasn't happened, YET. Please, try to get into a recovery program, once you become active in your own recovery, the rest will fall into place. You will be able to walk through the financial hardship, and each day does get better, I promise. Hang in there.

Yes, you absolutely can have physical withdrawal from gambling. It's an addiction, an illness. It can take quite a while for your brain, body, mind, and heart to heal, so depression, anxiety, irritation, panic, lethargy, etc. are all normal withdrawal symptoms. With support and time, it does get better! I noticed your location is Ohio, so here's a link to resources there http://www.ncpgambling.org/state/ohio/
I absolutely had to have help to get out of the despair I was in from gambling, so I hope you'll reach out to find support in your area. Leapyear22 is right--once you start working your recovery, things will eventually fall into place. For now, take a deep breath, be kind to yourself, and just do the next right thing to stay away from gambling one day at a time. Glad you posted. We are here for you!

First, although it may be a stupid act, I doubt that you are stupid. I did some bad and stupid and self-destructive things while gambling, but it does not make me a bad person, I am not defined by my past behaviors. A facet of recovery is often forgiving ourselves so that we can befriend ourselves. All you need to worry about is NOT gambling right now. Just for today.
On withdrawal: Absolutely, I went through withdrawal, which may vary from person to person as to when, how long it lasts and intensity. We are actually addicted to the organic chemical, dopamine, it comes from our own bodies and gambling makes our bodies flood our brains with it, in doses that are not natural to sustain. I also believe that withdrawal symptoms are part of what the experts use to define addiction.
I did not begin to feel better until around 3 to 3 1/2 months of abstinence. I had huge mood swings, depression, shame, and a flood of emotions and cried at everything for several weeks. It helps to take actions that will make you feel better. Allow yourself comfort food, bubble baths, sleep when you feel tired, eat when hungry, call someone when lonely or angry. Anything creative can relieve boredom, anxiety and urges. Reading a daily affirmation, exercise, singing, dancing, communing with nature and doing something for someone else, are all free and can make you feel better.There are quite a few educational videos about dopamine, addiction recovery etc on You Tube and TED.com.
I venture all of the people on this board have major losses, I was completely bankrupt financially, emotionally, physically, and spiritually. The money is never anybody's biggest problem, if we take care of the other three, the money will get worked out.

It will help you now and later to record this memory of how you feel right now - journal it. Reviewing my "rock bottom" is part of what keeps me abstinent today, I never want to feel that way again.

Here is the national problem gambling hotline: 1-800-522-4700 they can tell you if treatment is available in your area. In my State treatment is paid for with lottery dollars by State law and it is available for the gambler as well as their significant others. (Loved ones can get help even if the gamble is not seeking help.)
The high interest on the money thing, is that legal? It is not in my State. It's called predatory lending.
Hang in there, the most important day in our recovery is Day one, the day we decide to do something different.

Thanks everyone so helpful and affirming. Still feel like crap but all your input really helps

Everyone here has been in your shoes. We've all felt the humiliation of losing, lying and regret. We've all gotten in over our heads. We've all failed dozens of times trying to beat this thing. For 3 years I lived for gambling. It was all I did. Every day I was at the casino. It took hold of me in ways I can't even describe. It was like I was possessed. My addiction started exactly how you described. I grew up in a state where there are no casinos. I moved to Michigan for work and immediately found myself with 15 minutes of 4 casinos with several more in Ohio and on the western side of the state. I started out going here and there for fun with some new friends. Without warning I found I couldn't stay away. It just took over my life without me even realizing it. I blew every dollar I had access to at the casino. I was out of control. Even when I did win large amounts of money I would stay until I had given it all back. Gambling was all I did. It took trying many different approaches until I was finally able to stay away. I am coming up on almost 20 months of abstinence from gambling. I know it seems hard right now but it can be done. There are lots of tools available to you. If you read up on this forum you will see many of them discussed. I would recommend trying them all until you find what helps you the best. The most important thing is to stop and reclaim your life. Don't let this disease destroy you. It is all consuming. It will take years to repair the damage gambling did to my life. Even so I still feel infinitely better today than I did on my best day gambling. You can do this! We all believe in you!

this is why i continue to read and re-read these posts,
