<human>: I don't know if this is the right place to post this but here goes anyway. 

I basically can't keep people close to me. Nobody ever feels worth keeping. This isn't just an issue with platonic relationships either. If im getting somewhere with a girl it feels great for the first few weeks but I eventually get a sick feeling in the pit of my stomach and I end up calling it off only to realise a few days later that I did like the girl and now I feel sad for ending it. This always happens. No matter with who. 

I always end it because I begin to doubt that I like the person. The feeling gets worse and worse over time until I end it, then I feel relieved and after a week I regret it. 

I don't want to be alone, and this feeling makes it impossible for me to have somebody. The longest I've kept a friend is 1 year and for a love interest I managed 3 months until the feeling of dread made me end it. 

I have no clue what's wrong with me and I'm really just looking for some help with this as I can't stand being alone anymore.

<bot>: I get a feeling of dread in the pit of my stomach when I get into relationships with people. I feel like I have to end it and I always do. It leads to me being alone and I can't take it anymore.
