Feeling guilty because I don't have the energy to talk to my partner

So we were together for a year and a half the we broke things off for a year then got back together, she knows that I m bipolar but doesn't quite understand or hasn't adjusted to what that means practically.

So right now I m going through an absolute crash and haven't had any energy to talk tor to contribute to anything in a meaningful way for weeks. And I can feel that she's getting a little annoyed and in turn that's making me anxious and I feel like I should break things off again.I can deal with things on my own but the anxiety and the disappointment is killing me.
