Deep down I feel like giving up

I'm a few months into my 24th year. I told myself that when I turned 24 that I'd go out and lose it on my birthday, like some odd resolution. Never did. I told myself for years since I was maybe 18 I'd lose it that year.

Now it's not even about the aspect of sex. It's that I don't even have experience in simple things, I never kissed anyone or even been on a date. I feel like I'd be a pity case or just undesirable as a whole.

How did I let it get this bad, what'd wrong with me ? I feel far behind, I don't know how- I don't want to explain to someone that I like that I have 0 experience . It's embarrassing.

I feel embarrassed of myself, I feel sad. I'm tired, tired of caring so much. I hate going to events and gatherings and being the only single person in my age group or the guy without kids.

I'm tired, I feel so frustrated
