Op, first I am definitely not “ victim blaming” in what I’ll say. I’m sorry you’re in this situation and it is definitely appalling for you.
imhe, it does sound like this issue is more to do with how you initiate social interactions. And that You need some help with this specifically
it is unusual to not make friends at uni and this is something that should alert you to needing some help to sort this. It sounds like you’re still quite young , so you need to get on top of this to reach your full potential in life.
we are social beings. It is hard wired into our psyche. Trust is the glue that makes that work. We use “ thin” trust daily when meeting random strangers or just in our expectations of dealing with others. Over time, as you have more interactions with that person thin trust develops into the thick trust between friends and close social relationships. But trust is reciprocal- we are very tuned to pick up signals that someone doesn’t trust us, and in turn we don’t trust them, we hold back to ensure we protect ourselves etc. and that leads to a downward spiral of disconnection with the other person
all humans have a need to be socially accepted ( with exceptions of specific mental conditions). We are hard wired to be accepted and trusted ( thin trust) from the moment we meet someone
small signals are important to ensure the other person knows you trust them by default. A smile, eye contact, mirroring their body language, and that’s even before you get into talking.
what you wear, what you look like will have very little to do with such a widespread persistent problem. Ok, they’re a few prejudice people out there that are rude to people that look “ different” ( weight, colour, disability etc) , but you’re not talking about a small number of bad encounters we all have. Forget what you look like - it ain’t that.
so 2 things I think you need some help with
- The fact you’ve been able to switch off those signals that are inate to us to make those social connections- like stopping smiling. Smiles are contagious for a reason and that’s a hard thing to stop. That’s a concern really.
- you are going into interactions from the get go with distrust and beliefs that you cannot connect . As I said, trust is reciprocal, people will pick up on that and in some ways will be afraid, they’ll be asking themselves same thing “ why is this person so standoffish / cold/ reserved with me” and will mirror back
I would be looking at help from a qualified psychologist ( NOT a counsellor) to look at these behaviours you’ve developed, and why. Then work with you to overcome them
