Idk why my life is ike this

Quick recap about myself

22

Single

I have studied from boys school and then after that I got into college

I didn't date anyone due to my nervousness and anxiety and being introverted

4 years I spent seing my frinds hooking up and having gfs and break up and going out on dates and dining out and exploring places and what not

Where I didn't

Now whenever I go out

All I see is couples

On a date

Riding bike together

Having fun

Sharing food

Making memories and figuring out their life partner and all

And here I am single as ***

Idk why am I like

I don't think I am that bad of a person

But my heartaches when I go out literally

It makes me cry man

I don't know why this happening to me

Also I am preparing for an exam rest all are also doing something in their life

Social life has also took a hitbsince college is over and I don't have any friends either

Idk what to do

I mean I wanna have a proper conversation with someone and enjoy with someone whobi really am
