How can I be extroverted?

TL;DR - I get annoyed by extroverted people, can't escape the situation I'm in, and want to learn how to cope.

First time, first post. I know I'm depressed, so let me just get that out of the way. I'm on meds and have been to therapy; neither have helped.

My issue is that I'm introverted, and after spending time around extroverted people I begin to get irritated and angry and just want to escape.

My main issue now is I have a very extroverted 5-yr-old who doesn't shut up or leave me alone. I don't want to hear this is a typical 5-yr-old because I've been around his friends and other kids who are not this outgoing! Because I'm unemployed (can't work due to injury and being laid off) I'm around him all the time when he's home sick or on the weekends, and after a few hours I get beyond irritated and want to scream! If I try to go into a different room to recharge and get a break he's constantly yelling for me or follows me and bangs on the door. I can't even walk away without him wanting something from me or wanting to tell me something. Telling him time and time again that I'm going to go do something real quick (just so I can go and try to recharge), he will not listen when I tell him to stay where he is and not call for me. I've tried everything I can think of to get him to listen.

I also have zero support. My wife has gotten mad at me recently and told me I need to get my sh** together because it's always like I'm in a bad mood. When I mentioned that sometimes I need a break, she said that was ridiculous because I get a break when he's in school. However, and this is me saying this, I do not get a break the several days when he is home sick, at nights, or on weekends. I have now come to the point where I don't enjoy being around him because I find I instantly get irritated.

All of this has caused me to depend on a substance called Kratom that puts me into a happier mood for a brief time and gives some relief. I'm not addicted to it, I just use it when I'm in a really bad mood so my wife doesn't give me crap for being crabby.

So, The only thing I can think of is that if I can find a way for me to be happier and not need a recharge around extroverted people that this may help.
