Trying to manage too many things at once. First priority is get very good grades in school. Otherwise, going to school is a total waste of time. Good grades give you a MUCH better life ... one a lot better than the one you describe. Screw just about everything else ... good grades, .. TOP PRIORITY .... even ahead of happiness. Happiness will come later ... I promise.

Cannot live without money. That means job, benefactor, winning lottery, crime. Concentrate on the job part .... KNOWING they can be hard to find. Keep looking. Get yourself in a better mind frame and study how to attract a job. There are TONS of 'em around. I don't know where you live, but Google:

Work at home jobs

There are now tons of legitimate opportunities.

None of us asked to 'be here'. So what? .. we ARE here, so make something good out of it.

"I’m angry all the time, sad, bitter, and resentful."

Yeah, .. I sensed that. And that could be the very reason you are unhappy ... Hmmmmm?

Soooo, get yourself to a doctor and find out if there is a medical reason for that state of mind. There COULD be .... and if so, it needs to be treated. Otherwise, you live your entire life with it ... a life much like what you describe in your post..

Get busy fixing things. Take each one of my suggestions to heart, ... especially the medical item.

I'm trying my best to forgive many people that I love with all my heart because I want to let go of the resentment and pain.

It's been a process and it's not easy, but I'm already starting to feel better. And note that forgiveness doesn't necessarily mean you're okay with the bad things that have happened, or even that you want a relationship with the people who hurt you. It's so you can go on with your life not continually arrested by those things.

Life is hard but it can be beautiful, too. Give yourself a chance to experience the good stuff.

Do not try to do things by yourself. Find a tutor for your school work. Find a employment councelor to help you get a job. Look at Youtube. There are millions of videos teaches how to make money. Social media have groups and schools about how to make money. Find a mentor to help you with your life. There are free mentoring. I heard a lot of people say they are doing bad in life. You are not alone.

I must agree life is way harder than I ever thought it would be. At the same time I've experienced stuff way cooler than I ever thought I would experience. What you are going through is called a trial. They suck big time but if you can get through them in one piece then you become a much stronger, kinder person - it's weird. Ignore all the bs in your brain and do your best. Good luck with school. When it comes to the money issue improve your financial IQ - yeah, I didn't really know such a thing existed. Don't spend too much; don't borrow money from anyone. Make sure you have money for necessities by not spending too much on leisure/ entertainment items. It's all easier said than done - I know.

Sorry to hear that you are struggling. It is hard to concentrate when emotional pain is a big part of your life. It takes awhile to work through past situations and find your way. I hope you can get the help you need to do better in school and focus on what you are learning. I agree that a tutor might be a good solution. Some of the libraries are offering free tutors for certain subjects. Don't give up on the job search. Tell everyone you know you are looking for a job because word-of-mouth is free advertising. Being thankful can also help in your recovery.

Sorry I am so late. Thank you everyone, your words seriously help.
