i'm not sure where to go...

i've been dealing with such bad anxiety and my depression has been my worst nightmare. yes, i'm in therapy, but i'm not on medication because i was told that it was mostly situational and SAD. i'm not sure who to talk to because none of my friends understand and i feel that i can't trust anyone to talk about it. i can't even talk to my best friend about it because she's preoccupied by her new boyfriend. i just feel so alone and i hate that i feel like i'm the only one that goes through this around me. i want to be done talking about it, but people don't understand that this is all my mind goes toward. i'm not trying to be selfish by only talking about myself, but i just need support.
