How to actually cure desperation? (36M)

We all know desperation kills attraction, but no matter how much I try to investigate I never found a cure for desperation. And this is what's holding me back.

I haven't been on a date in more than 6 years. I tried to work on myself and put myself out for more than 5 years. Read tons of books, joined activities I like, progressed in my career, moved to a new apartment, I travel as much as I can, I meet new people regularly. And I do talk to girls, in fact I met two of my best (F) friends in the last years and we talk almost every day.

But I am still desperate to date. And my desperation is skyrocketing now with the clock ticking. I am running out of time to have my own family, you may say I have a lot of time but I didn't see any minimal progress in the last 6 years.

I hope you can help me with ideas to cure desperation. I feel Any recommendation is welcome. I read some books in the topic, I talked to a psychologist and after few sessions she told me this is it and to keep going with my attempts until I find someone who likes me... Never happened.

I'm very social and I meet new people regularly but I am desperate and I can't attract anyone. I only see years going by and I am exactly in the same spot.
