Lost I have thought...
As someone already said, you are very social here, very compassionate, helpful and a good friend :). So you are capable of friendship.
Next, you mention before your accident or before being aware of your past, before ptsd symptoms that you lived away, on your own. Knew your neighbors Etc.
You mention the squeezing in your stomach at the thought of being around ppl, in public always having an exit plan. That in itself sounds like panic. Which can be eased by exposure over time.
Having said all of that, I have tried to think of what makes it easy for me to chit chat with strangers. I am a typical southerner...never meet a stranger. Tho This last recent trauma incident of robbery and kidnapping at gunpoint 10 months ago has slowed me down a lot. Always hyper vigilant, fear of public places etc.
But that didn't change my ability to make chit chat with someone in a grocery check out if I went with my husband and knew I was safe. Does that make any sense? It's like separating the fears. The fear of public and the fear of talking to ppl. Separate them and really examine what about each is so fearful.
To deal with the fear of public places A little at a time my t has encouraged me to go to a grocery sore for a set amount of time. Start with 5 minutes and increase gradually. He says no matter how you feel! Grrrr but it works.
But my guess is that for you it's not so much about public places. You go to work, hell you even go to Walmart! Lol I can't do that one.
I think for you the change is that you are afraid that if you make eye contact with ppl, or speak to them, they will see through you. They will see all things bad inside of you...your past. All the things you think you did wrong...everything you feel shame about. I think this and I may be wrong, but in all my small talk and chit chat with ppl I can't make eye contact for this reason. The eyes are like the window into the soul and I am afraid everyone will see all the bad that I see in my head.
I know so many ppl. I grew up here. We ran a business that was open to the public, and as they say "fake it till you make it". I was a social worker before the "fall"! WTH how did I do that. Home visits and all. But that was before my breakdown. Before I KNEW who I was and all the shameful things. Talk about doing a total 180.
I have one very dear friend of 18 yrs. I happened to meet her in a psych hospital in the middle of my meltdown and she was in hers. So we already had common ground. We started off seeing the worst in each other so it could only get better. :)
Anyway, I didn't mean to get so wordy, but whether any of this resonates with you or not, I hope that you can really look at the WHY and take a chance.
And as we already talked about once, the dog park is a great place for you to start. :)
And I just got a coloring book too! I broke my foot and I have been in a cast on my right foot for over a week so I can't drive. I've got serious cabin fever!
