Honestly feeling so old at times for real and feeling really down. What should I do?

I am 23 and have been feeling really old at times and feeling running out of time. Its been exactly 2 weeks since this girl Sharanya who is 19 turning 20 in 2-3 weeks havent replied to me on Instagram and she restricted my account too and I really liked her and knew her for 8-9 months. I never had a girlfriend before and only had one first date over 6 months ago at the age of 22 and it didn't work out. I feel like i missed out a lot and suddenly i am 23 years old now. Now the only girl I have is my crush Akankshya who is also within 21-23 age range and we have brief conversations and i even complimented her too but the fact that she is so pretty almost model like and I look like a nerd makes me feel that I have no chance with her. After Sharanya ghosted me, i have very less hope that she will even like me back. I am craving for a hug from her but I am shy to ask for a hug from her.

I had crush on another girl in the same classes I go for 7 months whose name is Anshika and she is also 23 now but was too shy to say her that but I think she already knew as I gave her chocolate twice and she would call me cute too and I would pull her cheeks. But 2 months ago after she came to know about my crush on Akankshya, she has been ignoring me so its safe to say i have no chance with Anshika as well as she isnt even talking with me anymore and only spends more time with this guy in our class named Vaibhav who is 24 and i guess they are probably dating as i always see them together. Idk whether Akankshya is even single or not either. Its already April 2024 and i am getting older and feeling as if I am missing out so much. And honestly I am still missing Sharanya and still unable to move on fully from her.
