There is some good advice here, so take this as an "in addition to", not an "instead of".
It may be worth checking if you are neurodivergent in some way. A number of people close to me have had mid-life realisations that they are on the ASD and/or ADHD spectrums.
Naturally not everyone that struggles with social skills will be neurodivergent, and vice-versa. But there is some degree of correlation so it may be worth considering.
Oddly, TikTok has been a pretty accurate diagnosis tool. If TikTok shows you a number of very relatable neurodivergent-related videos then that may be a useful starting point. If it just shows you a bunch of dancing people, then ¯\_(ツ)_/¯
