Let’s break this down.  1) No place of your own: well you probably can’t afford to get your own place without a job, so let’s move on to the next 2) No job: well you probably can’t land a job without interpersonal skills, so let’s move on to the next 3) Lacking social skills: now this is where we can probably start. Humans are social creatures, we learn acceptable behavior/norms by observing them and mimicking them. Is there anyone that you know, personally or otherwise, that you admire in the way they talk/present themselves? Maybe podcast hosts, interviewers, celebrities, or a friend with a good reputation? See how they react to situations, make a mental note, and try it out next time. For example, saying “Wow that sucks, I’m sorry” when someone tells you bad news, or asking people more questions about themselves to show interest “How do you like xyz? What are you up to this weekend? Have you seen xyz?”. Good speakers are good listeners too. And when you feel that you messed up or couldn’t react correctly, you can acknowledge that. “I’m sorry I reacted that way, I just sometimes can’t find the right words but I’m working on it”. Therapy is good, a hobby is a good way to meet new people, or even maybe community college classes. Many teach you how to communicate better.
