BlueMoon - I am a mom with kids in college and I can tell you that no matter how independent your kids are, they are the center of your universe. I would put a bunch of money on the notion that your parents miss you as much as you miss them. Call them and be honest with them about
what is going on.
Now, if I may, speaking as someone's mother -
1. Getting off of your meds will not make this better. Perhaps you weren't on the right med for you and you need to find one that is more effective for you. Meds are as individual as we are and what works for one may not work for all.
2. Stopping your counselling will not make this better. If it was "making it worse" maybe you really are getting closer to what you need to be talking about
but now you are running away from it. Does that make sense to you? I am not trying to be harsh. That comment comes from my experience being a mom of a very homesick daughter who was 3000 away at school.
3. You have to take charge of this situation. This may be the first time in your life that you have to be in charge but allowing yourself to get isolated without a support group will not make this better. I understand how difficult it is to be motivated and strong when you are scared and it feels like you aren't in control. It doesn't mean that you don't have to do it. For me, I started to take back my control with little things. I made sure that I made my bed every day. It was a little thing but I was successful at it and that made me feel successful.
Walk in harmony
