I'm too clingy and annoying. I'm uninteresting and boring and my boyfriend sees it. I'm sure I have BPD as the symptoms match how I feel and I know that this must be the case. And I don't know what to do. I don't know. I don't know. Help?

How do I not have these bad mood swings? 

How do I not go crazy?

How do I not be so clingy and overattached?

I know I must be weird. But I can't control my overreactions and how he is busy and then I am not good enough. I'm losing my mind and he sees it. I'm losing myself and he sees it. 

I'm done. I'm done. I'm done.
