Why am I so stupid and clumsy !

I feel like everything goes wrong when I’m around... my ex and I were together a while and every single time we were together something went wrong and it would almost every time be most likely my fault in some way. When we’d argue it would be because of me dropping, spilling or saying or doing something that was wrong so for example id tell him to go somewhere and end up giving him wrong directions because I didn’t think of telling him where to go sooner. This was just one of the many things that I’ve done to cause an argument. I just feel useless and I can’t do nothing right.

He broke up with me and never said why I’m certain it’s because of me causing him so much stress just being myself and he doesn’t need to carry on with me when he can be with someone else who brings happiness to him.

Anyway today my dad got into a minor crash but I feel it was my fault because I wanted him to take me some where but if I didn’t ask him to take me then we would have avoided that way completely.

I just feel like I’m cursed and I do dumb things that fall back on me or don’t think and then it just causes friction between me and other people. I really want my ex back to somehow prove I’ve changed but at the same time I don’t want to because it’ll just cause him pain again being with me
