I was just making a sandwich and humming and thought to myself "aww, that's adorable" and then I immediately felt extremely sad like I was about to cry and I don't understand why I have such an intense mood swing.

Sometimes my husband (small gay man, super adorable by default) will be doing stuff like dancing or humming or anything that I think is \^-\^ cute (if that makes any sense) and it will make me want to sob. I have no idea why this keeps happening. 

And then I'll have extremely intrusive thoughts about people being mean to him which also makes me want to cry. There's really no reason for me to have these thoughts as he is well liked, but it's just a weird thing that happens to me. 

I wish I could make this stop so I can just be in the moment and not get sad. He's the perfect partner for me, we get along very well, he's very patient with me and understands BPD, and he'll tell me that he's not going to leave me as reassurance when I'm feeling down, and that too will cause me to want to cry or get intrusive thoughts of bad things happening.

Any thoughts or advice would be welcome. Thank you.
