Can someone help?

Hi guys I don't know why I'm posting this honestly but I hope someone can try help me figure out what's wrong with me.

So basically me and my girlfriend she is the best honestly but at times I could make one minor mistake to her especially and she wouldn't even care my I feel so fucking awful about it like even today for example I was talking to her and she said shut up completely joking and inside I felt like I wanted to die like she hates me so much and doesn't want anything to do with me.

my whole body starts to tingle and I get this huge feeling of sadness and disappointment in myself I eat myself alive for it I think I'm the most awful human for even annoying her or disturbing her when she literally said it in a joking way I'm not trying to say this is anything from my girlfriends side I don't think it's her causing it I just don't want to upset her or make her hate me I keep telling myself your a horrible human you don't deserve any of this not her not anything I think I'm completely worthless and would be better off d3ad.

Can anybody help me please this is eating me from the inside out I hate it so much I'm slowly hating myself more and more and I hate disappointing her especially I feel like she is going to start hating me and leave me.
