I feel very lonely because of my current love live

I am 28 years old and never being into a relationship which has made me feel very lonely.

I have never have any sort of intimacy with someone or even a kiss, every time that I try to meet someone it just rejection I understand is part of life and all but when it happens again again and again it makes you wonder

Is there something terrible wrong with me?

Am I coming way to desperate?

Am i really that un attractive?

Life has been really hard on me especially my last years, I don't enjoy any holidays or events since I don't have any family close by and we are not close at all, I cry myself to sleep way to many times from this pain.

I enjoy my own time by myself but part of me wishes that I can share moments with someone.

I've done things by myself like going to restaurants watching movies and events but it always feels like something is missing. Part of me knows that is dumb and kinda unfair to put my "happiness" on another person and I should not be looking for a relationship just to calm me down but it hurts, it hurts seen couples being happy, I am not mad at them.

Makes me sad that I have never experienced or even felt that someone genuinely cares about me and loves me for who I am.

Getting tired of feeling like this every day, somedays it's just to much and I break down on tears, I try to keep it together and bury my emotions. Most of the times I am able to do this and pretend that everything is fine but I know I am not fine and I am really broken.

I don't know what to do anymore, I have try various things that would help to either improve my "love life" or just myself but nothing seems to be working I am really scared cuz my head is just telling me to end it all.

Been to multiple psychiatrist and doing a lot of therapy nothing seems to be working. I am really scared and don't know how to continue.
