How do I stop feeling so insecure

I’m so of feeling the need to get reassurance from my boyfriend and he’s sick of giving it to me

He literally told me I’m annoying cause of my anxiety and my need for him to tell me I’m all he wants

Idk what to do to help myself. He won’t even help me anymore. I don’t ask for too much reassurance or anything just every now and again and he’s just fed up.

I used to be so confident and he hated it and said I need to be more humble so I became more humble now that’s annoying. So should I just go back to being my confident self and not give a fuck anymore?
