Please help me

I don’t know what’s wrong but my depression is getting really bad again the slightest thing can go wrong and I’m ready to have a breakdown or end it all, I don’t know what to do I’m upsetting those around me and I can’t help it. I’m really trying but I’m just so down at the moment. I was wondering g if maybe the pill had anything to do with it? Because it started back up just after I started taking the pill.

Please can someone help I don’t know what to do
