Welome to the forums. I think it's great that you've found us...even if you're no longer experiencing the pain anymore, it has obviously impacted your life in other unseen ways.
I understand what you mean when you say you're stuck in a loop of hopelessness....it often can feel that way when you wake up every morning in pain, and it never goes away. It's possible to feel like that's all you have to look forward to in life...but you've been given a wonderful gift, in that your pain is gone and you no longer have to feel "trapped" by it.
If you are still feeling hopeless, I would suggest you do the following exercise: take a piece of lined paper...on one side, write down all the things that your pain prevented you from doing. On the other page, write down all the things that being pain free can mean for you.
Sometimes, seeing all the good things about being pain free written down make it more tangible. I'm sure you'll find your second list to be much bigger than the first one. After you've done this and you've had time to reflect on what being pain free means, ask yourself what the three biggest things are that you want to accomplish that you couldn't do before. The more you get your mind thinking about positive things, the more your general mind set will change.
You say you feel that nothing you can do will make a difference, but I'm going to challenge that. Are you physically able to volunteer somewhere, doing something you love (and don't put obstacles in the way like lack of transportation or lack of money...I'm just asking if you are pysically able to volunteer)? If the answer is yes, then you are making a difference.
Start thinking about the things that make you grateful. Start thinking about the physical things you couldn't do before, but you are able to do now. The more you move your thoughts to the positive side, the better you're going to feel.
As for your job...perhaps you can't find a position that uses the skills you've just mastered at school...but that doesn't mean you can't find a job doing "something" you enjoy. Go out there with the attitude that the world is your oyster, and you'll be surprised at what you can do.
All my best to you...
