There seems to be agreement that a hypomanic or manic phase won't last forever. What do people think about depressive phases ending eventually?

I've been in a depressive phase for about 3 months - - just wondering if it's probable I'll get back to baseline someday. I guess, logically, it would seem the answer is yes. I'm not even sure what my "baseline" is anymore though; I just know I'm not there right now but not despondent either. Somewhere in between.
