I recommend:
Strive for the best health you can. Clean up your diet, get some exercise every day ( a walk is perfect), and get all the sleep you can. That last one is a tall order for some of us.
Keep records. Learn how to use a spreadsheet to log what you eat and when, your exercise activities, how much sleep you get, things that happen in general that are worth noting, etc. You will start to see that perhaps certain foods wreck your sleep for a night or two, or perhaps walking in a certain area causes undue anxiety, and so forth.
Learn to cook. Not only do you have total control over what is in the food you eat but it helps foster executive functioning to be able to plan what to cook, gather the ingredients, and then combine them according to the recipe. Plus it gets you a giant step closer toward independence if you are still at home.
Search for a support group in your area. No doubt you probably already have but if its been more than 6 months since you did, its time to search again. Never give up hope.
Finally, if you are not taking an anti-depressant, see a doctor and ask him to write a script. It does not have to be a psych, a general practitioner will do. Without an anti-depressant your anxiety is probably thru the roof and you don't realize how much better you can feel. When I started taking mine, I wanted to remove flouride out of the water supply and put amitriptyline in! I wanted to know where it had been all my life--and I was only taking 25 mg!
In general, take life one day at a time. Set long term goals but still, concentrate on making it one more day in your classes or at your job.
I hope these will help.
