I am bothering with anxiety and depression

If you are from India you would be can better understand

At the end of 11th and start of 12th (by Jan 2025 in coaching) i joined a new coaching then I got a crush and some classmates and my crush was physics teacher's sister whom I liked too much a classmate also likes her and then he and his friend making laugh on me getting me emotionally unsupportive and there's my anxiety started and then things get too rumbled that's why I didn't get my crush even as a friend and he got all over her.

And 6 months later there was a new girl get into chemistry classes and I was that time thinking that I won't get into it i mean any kind of relationship or something but she started to talk to me then love gets really arose in me for her then we are too good friends to around 6 months but then I get knew by her sister that her Male Best friend is getting to propose her and she is ready for that . That's why I proposed her before him but not directly so she wouldn't get that I said after that I after 2 months proposed her directly and she didn't replied properly but that same day her boyfriend is messaging me and telling me to don't bother her i said ok cause it was sign of rejection but i really love her but she won't and few days she talked to around 6 minutes on call I was surprised I asked who contacts after that incident she said me . Then I have nothing to talk to that's why I told that all the thing to my sister she said she likes i said she have boyfriend and my sister said that talk to her she is liking i said i don't think so if she likes me she would tell me Ohk as you said i will talk her but not about that she said okay but I haven't talked her yet

I told the story in too short so forgive me but maybe you got my feelings and that's not all thing bothering me it's just around 20% of my problem
