It's amazing what going away to school will do for you. Sometimes it's the best thing and sometimes it's not so good. I think it's important to realize that, if you are away or not, if it's not working for you then it's perfectly acceptable to take a year to yourself. I think life is so much more flexible when you're as young as you are.
I have found that lately, I had to ask my husband to make sure I take my meds....and he does.
If you can ask your mom to do the same, I strongly encourage it. I know they take a while to kick in and it seems futile in the beginning, but they might be exactly what will change your thinking enough so that you feel more in control of what's going on rather than just watching, helpless and uncaring.
