How much more stressful is college on a non-traditional student, and what are some good ways to deal with college stress at 30?

I spent 11 years in the service and multiple deployments to Iraq, Afghanistan, and other places where I saw combat. I wanted to retire from the military, but not in the manner that I did. I was medically retired last year and I know that I am having issues with readjusting to my new life, have post traumatic stress disorder, and traumatic brain injury from some blasts during my last deployment. My problem is that I do go to the VA and I am trying to get my life moving forward, but it seems they just keep giving me a handful of some pretty powerful pills and are not really doing much for me. I have been on and off several different sleeping, anti-depressant, anxiety, and a lot of other stuff that I don't really know about for almost a year now. Are there other resources available for disabled veterans to use other than the VA? If so how do I get in contact with them? And should I continue taking all this medication that makes me feel like a zombie?

I suffer from overeating constantly and binge eating. I've gained a considerable amount of weight and have tried to get my eating under control as a result, but when I try to stick to a diet, all I think about is food. I can't stop thinking about food until I eat something; when I try to ignore it, the urge doesn't go away. It's hard to think about anything else, so I usually give in. I feel out of control, like food controls my life, and like I'll never get my weight down to a weight I'm comfortable with. I don't have health insurance, so I can't get psychotherapy. How can I get my eating under control? Do you know of any free accessible resources I can use like books or websites that would be helpful?

My roommate attempted suicide and I found her in the bathroom. She wants to come back to school next semester but I don't think she is better even though she has recieved professional help. How can I ever trust her again and feel comfortable? I am scared constantly at being alone with her. What do I do? How can I tell her about my fears?
