Might be too mentally unstable for a relationship

So I (24M) have been with my boyfriend (31M) for 9 months now. He’s a great partner, and we match on so many levels. And it honestly feels like it could be „it“ (it’s my 2nd relationship).

So I have a history of depression which I got figured out before my first relationship so never had to deal with that. I’m on meds but I still feel like I’ve been mentally unraveling these past few weeks.

We never fought, had a few minor things to work out but that wasn’t an issue. But recently I noticed myself being really sensitive about things that shouldn’t really be a big deal. Yeah I’m not too happy about some of it but it’s not worth crying about. Because I don’t want to be a nag I keep it in.

Today one of those moments happened and I really started to question if I’m even in the mental state to be in a relationship. I don’t want to burden him with a version of myself I really don’t like. He knows about my depression, and how that was like for me but still hearing about it is a lot different than living through it.

So yeah, in short, idk what to do. There’s this great guy (who honestly is the reason I’m holding it together) who loves me and I don’t know if I might not wreck it
