I was too (and still to a degree am). I once shared a rental with a female socialite. She said she accepts EVERY invitation to go out and suggested I do the same.
Getting used to being around people and being in awkward situations where you have to talk to randoms will develop calluses. It is a skill you can develop by just practice. (public speaking is another example).
I look forward to talking to you in a random party! :)
One of my no-gos was going to weight room/area of the gym (I could tolerate cardio area) and one of the first homework activities things my therapist gave me was going to weight room and sitting for 5 mins to do some stretches. It was awful, but within a few months I slowly progressed to the point I was even confident enough to work with a personal trainer.
Slow but consistent incremental exposure to my triggers absolutely made a huge positive impact for me.
Due to a back injury (from pushing myself too hard, it wasn't just a shit-happens injury hencemy user name) that had me in horrible pain for the last 2 years I now get literal panic attacks in the environment I used to go to RESOLVE a panic attack. Ain't that some shit? My fear of reinjuring myself and going through the whole experience again is just too much. Even though I've learned my lesson and just desire to stay fit and functional I don't think I'll ever step foot in a traditional gym again. I like being able to sit down to make a poop in the morning without a burning ice pick shooting up my spine... I see what pro athletes talk about when a catastrophic injury and the painful and lonely recovery process robs them of the confidence to perform.
In between the pandemic and this injury the last 3 years have been very isolating. I've developed real fear of being in public from the amount of time I've been alone and physically confined. I feel like I got out of a 3 year relationship with a crazy overbearing girlfriend that no one could stand to be around and realizing how it just pushes people away.
Is getting better but doing things like progressing from a coffee to-go from a cafe, to actually sitting down for prescribed lengths of time and observing the waves of anxiety has been... interesting. You have to continually and willfully push your boundaries as you said but in safe increments the same way you increase your lifts in safe manageable increment. But it's hard to quantify how much more difficult one social setting or situation will be versus another. What's the "add 5 pounds" for exposure therapy? Haha. I'm sure it's different for every person.
I work with a therapist and it's going to be a process. Just started doing in office visits again. Social calluses indeed.
In the same way I associate discomfort and stress with progress in powerlifting (and subsequently in physical therapy) I try to tell myself that I'm not going to improve socially by putting myself only in comfortable situations.
Good luck. Looks like you've got a program that is working.
Sitting at home watching Netflix all evening and doom scrolling won't get you invites.
