Well tbh some people do care. But what you have to ask yourself is, do the opinions of those types of people really matter to you that much?
There are shallow people out there who will judge others for stupid, superficial things. But unless you put yourself out there (and I mean the real you, not some version of you that you think others will find acceptable) then you'll never meet the people who will like and accept you the way you are.
Also, you don't sound like a loser. The things you listed don't seem that unusual to me. There are many people that are living in similar circumstances to yours.
The future is here, and it's about a hundred feet above the Arby's.
