Not all that fucked if you're good looking and tall, I feel like social skills don't matter if you have those attributes. Otherwise, and that's the case due to the fact you're here, you're fucked
28 here also. My social skills are absolute dogshit, too. I've accepted where I stand in society, and you're right, it helps.
Why have such high expectations for yourself if you know you're going to fail to live up to them anyway?
i'm 25 and just this year am learning how to say hello to people i recognize and how to exit a conversation instead of just sitting quietly until the other person/people leave.
27 here. Been desperately trying to learn how to have conversations. Luckily I have an autistic coworker to learn with. I can now say "hello" and "bye" to people. It only took 2 and 4 months to learn to do it. Still cannot start a conversation or continue one without being awkward as fuck though. You can do it OP.
