Sounds like you have an introvert trait (in the Myers Briggs sense), which does
not mean despising human interaction but that even though you enjoy it, it’s taxing at some level (but you get some benefit at another level). If this is the case, the rejection comes from energy being exhausted (no one enjoys being exhausted) and you have to recharge your social interactions batteries.
At some point you may have intuitively associated meeting with people with that exhaustion and balanced your NN towards “not meeting” by default, hence the doominess feeling.
Active, conscious steps I took to get me out of that:
1. Recognise that being social brings you something internal (mood improvements)
2. Recognise that being social costs you some energy (depletes a battery)
3. Stop self-bashing for “not being social” at times (battery needs topping up)
4. Create a positive feedback loop instead of a negative one, by having less long/intense social interactions but more frequent, so that the battery never truly runs out and has time to recharge quickly
This takes time as the NN has to be retrained to break the default fight or flight reaction of staying in the safe zone at home.
It’s a bit like enjoying running a marathon and have a happy and relaxed mind following that, but the body is exhausted and certainly doesn’t want to run again back to back as it needs time to recover.
The introvert trait will not go away but the battery can be trained and improved in capacity, and end up looking forward to meeting people as long as it’s properly managed.
