Can you be depressed without getting episodes of it?

I feel like I lost my personality. I always feel like im not quite right. I have bipolar NOS because I've had manic episodes. My care coordinator always downplays depression when I mention it. I wasn't always this way. I lost my social skills, less motivation and I'm negative all the time. I have low self esteem and can't help but beat myself up all the time. Sometimes I show signs of mania when I'm not really manic. This causes me to do or say something that's slightly out of character but that's only because I'm so obsessed with changing my personality when I try it just comes out weird. I don't know if this is depression but whatever it is it just seems to be part of my identity now. Im a completely different person now. I have no interests in anything and when I try to pick up a new hobby I usually just give up. I know I probably don't have serious depression. But does it sound like I have it at all?
