I feel you. I'm there right now. It's a beautiful day out and I took my dog for a walk hoping to soak in the sun to feel somewhat better but I came in crying instead. I had stopped taking my antidepressant and it's just my 2nd day back on them. I giving myself a pass today and telling myself they will kick in sometime this weekend.
Hang in there, find someone to talk to if it's not your doc. Here's to better days for us both!
