You might also quite reasonably be confident in your professional and personal-friend lives, but be lacking some of that confidence in dating, since you haven't done it for years. These aren't transferable domains for a lot of people.
I was on dating sites and apps for several years before I started having any luck finding much, much less something serious, and every moment of it was valuable practice in an area that didn't come naturally to me at all. My career situation also improved throughout those years, sometimes faster than my dating skills, and I quickly learned that having a nicer car did me 0 favors while I was still uncomfortable on a date in the first place. None of that professional practice applied - was I going to talk about load balancers and HA strategies on the date?
I've had a long string of failures after starting dating (Post covid vaccine) and just felt so incapable of being next to another person.
It's like all this time quarantined as put my dating skills back to zero (not that they were ever good). I feel so broken, like shards of glass that cuts anyone who tries to touch me.
But you have inspired to to once again glue all my broken shards together and try and try again.
Thank you.
These are generally personality traits of someone who is not well adjusted. If you are the type of person who can become professionally and personally (think friendships and any other non-sexual relationship) successful, then you'll probably be fine jumping back into the dating pool even if you've only dabbled casually for a pretty long period of time.
