I'm a relatively normal functioning adult woman. I'm a professional, single mum, happy with my lot. I live a nice life, I have amazing family and really close and supportive friendships. However, I've never been good in relationships, all my insecurities come flowing out and I feel uneasy when I'm in one just waiting for the person to leave.
I haven't dated in 6 years so thought I was maybe ready. I met someone who I really liked and have been dating them for the past 6 weeks. But last night I got so drunk, in the house alone, was on the phone to them for a bit. I can't really remember but it seems we ended the conversation and I then tried to call them back, they didn't answer and so I text, 'fuck you then'! 
I then messaged, 'sorry I'm obviously psychotic so I'm just going to pull out of this. Take care.' They just replied, 'God'.
I am so upset, I've totally messed it up. I don't know why I got into that state, I'd been so happy all day. Also today was the first I told my friends about them and now I'll have to go back and say oh never mind that. It's like I purposely self sabotage.
I just honestly hate myself today. I don't even know whether to text them today or whether it's still salvageable or should I just leave it.
I'm so embarrassed.
