>>33280661 (OP)I'm in the same boat. It's not easy, you and me are both tainted now, so it won't even be as natural as it is for others.
What
>>33280682 said, but you gotta add discipline, and you have to add a third thing i will mention later. You have to explore all possibilities of hobbies, activities and opinions. You have to make a list and rate them. For example, pick up an instrument you like, make a wide list of songs played with that instrument, learn one well. If you liked that journey you now have one thing to connect with people through, if not you can connect with music players by saying the instrument is difficult. Try singing, make a list of popular songs and voice why you like or don't like them.
The third thing is, Despite looking like homework, you must spin in your mind that you're not doing a homework, you're not doing this to make "progress", you're doing it to explore and getting in that mindset is not easy.
Now the coldest truth is that, the mass of people are socially awkward, they just look like a big social circle because they are numerous, and all are made from the same. You are different, your tastes will be different, you can't help who you are because it's the only possible way you could have been. You will have a hard time finding people who end up appreciating things the same way you do, so the final skills to develop are patience and the ability to gauge people quickly, without investing emotionally in them, and without losing yourself in jadedness. It's as tough as it sounds and these final steps are eluding me.
Personally, Getting older is absorbing all of my thinking, so I lose patience. When I look back, a long streak of trauma left me anxious and without self esteem, so I invest intensely in people who don't deserve it, and shut myself from the possibility of meeting others. Having this clarity is but one step into the unknown.
