I'm still struggling with my breakup due to a manic episode

I'm still struggling with my breakup due to a manic episode -- and a long time has passed. I don't know what will make it stop. We were so close at one time. Some of the things around the manic episode that happened were her fault, and some weren't. Long story short, she actually kept me up the night before a film shoot which led to an episode and then behaved super unsupportively, so it complicates things for me.

It's been nearly a year and 3 months. I try not to look at our photos. But I captured so many of her so happy with me. We shared in a lot of happiness. It's a terrible thing that happened. I have paid such a heavy price since my subsequent manic episode and hospitalization. How can I make sense of it all?

How can I possibly get over this?
