Hey Brianna.
I know EXACTLY what you mean about the longer you're fighting depression the harder it gets. I've been on SSRIs since 1997 (holy crap, that's almost a decade!). I'm on Effexor now and it's kept me on an even keel, so to speak, but I still have very dark days. Relationships with "significant others" usually created more stress and anxiety for me. It took a long while, but I think the best thing for me was to finally be happy just with myself, and to be happy without depending on a girlfriend to make me feel worthy. After my divorce, I think I was trying to hard to establish my credibility as a "man" through being with a woman. Now that I'm single and not actively "looking," I'm beginning to enjoy me, my interests, and the ever-changing world around me.
Oh, and The Cellar, also.
Hang in there!
