Change is scary, even good change. If you feel like you are getting over your depression, a depression you say has lasted a long time, that could feel scary to you.

You are, in a way, becoming a new person. You are slowly becoming a healthier, happier, stronger, more adaptable person. You are starting to like yourself, take care of yourself and feel self esteem. So you are turning into a new improved you, and that's different, thus it leaves you feeling uneasy. Change, even good change, is stressful.

Also if all you've known is depression, to feel it leaving you can make you feel uneasy also. It's different. "Something's missing." But that's good!

You should try to find a therapist you can see while you are home, especially if you will be home for an extended period of time. You don't want to lose the progress you've made. And perhaps just the thought of being without the support of a therapist while you are home is also making you feel uneasy. You need to take care of yourself all the time, not just at school.
