I'm new here. I've been reading posts for a while but haven't really posted myself so here goes.

I started taking medication for depression in January and things have been getting better. I'm seeing a therapist weekly and things were going good. But this week I just feel liking I'm slipping back to how I was before. I'm not sleeping well and tonight on my way home I was ready to just cry for no reason. Is it normal for depression to come and go like this?
