Approaching 30 with no relationship: is something wrong with me?

I got everything but never love.
I was weak, underweight where you can see my bones.
So I focus on the only thing I can control, my skills.
I got the best university, the best Job, which was available to me on my skills and hard work.
With that salary, I fixed everything from my body to my looks and got confident enough to talk to everyone. Even went through the pain of wisdom tooth extraction 3 times and then braces at the age of 23, now I am approaching my 30s and still never found anyone who loves me. I was only loved by my parents for the money I brought in so it was too transactional to them as well.
Now this week I am looking at my whole life's struggles and now I question whether I am just someone who doesn't love myself or just my need for love is never going to satisfy. I am now thinking of just donating everything I got. As well as life, cause it feels the thing which I struggled to get has become a trauma or addiction.
I am afraid that I am so needy or clingy, that I am going to scare people away.
I had a simple fantasy, find someone at the age of 18 and have a relationship till 30 and marry her
