Is it normal to feel worthless when someone says they don't like you?
I live with my friend of the opposite sex and one day she calls me downstairs to talk. Apparently she thinks I have feelings for her and asks me if it’s true; fair enough but when I said no she seemed so relieved and even asking the question it was obvious what answer she wanted; it was almost like I could hear her screaming "please god don't let him like me". Afterwards she said the thought had been worrying her and that when she thought I liked her she found it “annoying”.
After she then asked me why I didn't like her in that way, which really caught me off guard. When I asked her the same thing back it seemed like she couldn't come up with a reason which is also really playing on my mind, either it's something so unflattering she can't bring herself to tell me or there's just something inherently unattractive about me that she can't put her finger on. I asked her again recently and she gave the answer “because you’re not 6’2 lol” which wasn’t much help.
Since then I’ve been feeling really worthless and rejected and keep thinking about how the idea of me having feelings for her was so repugnant to her and wonder what is so wrong with me. I think that if she had said something more along the lines of “do you like me?”, “no”, “oh ok it’s just I got the impression you did” I wouldn’t feel so bad but the whole sigh of relief and how happy she seemed has made me feel so bad about myself. This is especially the case seeing how happily she talks about the prospect of other guys she barely knows liking her.
I do already struggle with major issues like social anxiety, depression and very low self esteem and I wonder whether I’m overreacting but nevertheless I still feel like shit. It seems to be a pattern in my life where girls can stand to be around me but the hint of anything more makes them wretch and this has just reinforced that.
Is it normal that I feel like this? How can I feel better?
