I’m always sad

I still feel so sad and depressed all the time. My parents don’t make it any better with how they’ve been talking to me and treating me recently; today was one of the worst days being with them. They ignore me when I talk, or try to talk over me, and don’t even acknowledge when I’m trying to join a conversation.
My anti depressants I’ve been on for some time isn’t really working anymore, and I don’t know what else I can take—I’ve been through and taken about 5 different ones in the last few years. The one I’m on now worked for a while so I stayed on it, and now I just take it so I don’t go through withdrawal.
I’m going to a therapist soon, but I kinda wish I could get in sooner. I hope it helps at least a little.
