I think between your PTSD and your need to be wildly inappropriate and poke aka 'bear bait' you are currently a hot mess. Maybe not as evident IRL (I wouldn't know) but it seems internally you're a bunch of sparks just sparking away. The fact you don't seem to really get boundaries and always want to push does not bode well with your PTSD. It brings to mind the picture of a child flailing away wildly at nothing. Instead of compulsively trying to poke at people or get a reaction, rechannel that energy. Regardless of whether your are "as extreme" in real life the fact you have that compulsion to act out and are not really minding rules or boundaries or respecting other people is just going to perpetuate the anxiety and symptoms and social fall out you already get with PTSD. Basically, settle down. PTSD is kinda like ADHD in that way. You need to get grounded.
PTSD puts you in a high anxiety state where you get tunnel vision and all you can see is what your mind wants you to see and what your reality belief system tells you is the truth. Your body is basically on 'high alert' and on the ready for flight or fight.
I dated a guy with combat related PTSD his government assigned therapist basically did cognitive therapy which is basically controlled exposure. If X freaks you out, do 3 steps lower than X and work your way up. You have to desensitize your triggers. You also have to control your behavior so you're not intentionally provoking others
There are PTSD forums out there but I think they mostly give bad advice. People left to their own devices will opt for total aversion therapy, which basically means being totally non-confrontational even when necessary and avoiding life. That's not treatment or getting better. You have to reframe situations to not see them as a threat and retrain your response system down to the neurons. That's where meditation, breathing exercises, etc. come into play.
You could probably make a big dent in your PTSD on your own but any help, even a couple sessions with hypnotherapist, will be very useful. The best kind of therapy for PTSD (or anything, IMO) is cognitive therapy. Or the kind where you move your eyes side to side and reimagine traumatic events. Also, there may be community centers around where you live that offer free therapy. I knew someone getting his masters in marriage counseling who did counseling for free through a community center. At the very least, there should be a free meet-up for people with PTSD where you can meet them IRL.
