I get the impression I'm ugly

I've seen how women look at me, and if they don't already know me, it's a look of revulsion. My own mother calls me standing up straight "threatening." I don't think cutting women out of my life is an answer, but then there doesn't seem to be a good answer. I do wonder if I'd get these reactions if I was actually good-looking, though. Women who I do know who I've asked about this just tell me there's nothing wrong with me, but I can hear their voice change when they think they're telling me what they think I want to hear - it's like it breaks or wavers a little, and goes slightly higher like 'customer service voice' which just tells me there is something wrong with me that they just won't tell me about.

I am aware that I'm both severely overthinking this and spiraling into catastrophising. I just want someone to love me 😢
