I'm sorry you're feeling this way. When I got to that point I started therapy (this was in college). Then when the therapy had reached its max outcome at school, I was sent to the psychiatrist and he gave me anxiety meds and I felt immediately better. There was some tweaking of meds to get the right ones. For example propranalol made me more depressed than anything. So he put me on Citalopram and I've been on it ever since. A couple years ago I did two more years or so of Cognitive Behavioral therapy in addition to meds. That has made all the difference. I still have anxiety and it still gets bad sometimes but it hasn't been college bad for about 7 years.

I am a big proponent of Cognitive Behavioral therapy it is so helpful. It takes awhile to work and it is sometimes unpleasant work you have to do with the therapist but they work slowly and a good therapist shouldn't push you beyond your limit.

I hope this helps! HUGS. Also what helped me through bad times before I went to therapy was distraction. Stupid cat videos, cleaning the house, watching comedy TV.

Yes, I have to agree with Redvelvet, CBT works awesome. Within just a few visits I had come to see how messed up my thinking was. How I move to the worst case scenario in my thinking almost every single time.
Other than CBT, I've found having books and a text to speech book reader on my phone to be indispensable for breaking a cycle of bad thought. I just pull out my phone whether in the car, out shopping or whatever, put my book on and concentrate on the book. All the annoying background noise in my head is gone in minutes. If I'm in a store or someplace I don't want to annoy others, I'll use just one side of the set of earphones so the other ear can pick up anything I need to hear in the store. In the car or if I'm out for a walk I just let it blare out loud. It's great, I used to miss my books due to lack of time, now I'm back to getting a book finished every 7 to 10 days. Love my books I do.

For me I was a constant worrier and had OCD and could not stop it on my own. I would wake up in the morning and try to remember what I was worried about the night before. I had to go get help in my mid 40's and the doctor put me on prozac. I have been on it for over 20 yrs and have been able to control it. When I first started to take it I would wake up and say what was I worried about last night and I could not remember or did not care anymore. I lost that racing feeling of OCD. That is what works for me. There are many other ways that other people posted that are excellent also with out drugs.
