Maybe you're right. But I don't think acceptance has anything to do with you finding peace. You will only find peace when you can have something of value. Looks can be compensated with other things like money and status. So get those things. As for looks, you can always lose weight and gain muscle to maximize what you got. It's hard out there for men. Let's all get better...
Have you tried to consider the aspects of your looks that you can improve such as working out to develop an attractive physique or dressing better?
I’ve been rejected so many times and in awful ways, that honestly I can’t do it anymore. This is so painful, what I have now is resignation from social matters, I just wanna be alone, I hope you'all understand
being a loner is fine, nothing wrong with it, you are able to go and do whatever, freedom from chains of other humans, it's really a blessing.
