Can't handle this shittt

So yeah it all started in october 2021...i liked him so much but i was too shy to talk to him so on ther very last day of school i got his number and i was on cloud nine....we used to talk daily for around 2-2.5 hrs...everything was going so great we both loved each other so much...he was my weakness i was not able to listen a single word about him....in september 2022 i decided to move to delhi and he told me that he is going to a defence academy for 1.5 year and phone is not allowed there so we have to maintain a no contact for 1.5 long years and after my studies i'll be right back ...i said it's ok i will wait for you....then on 10 september 2022 my friend called me and said "hey i saw him today"..i was like wtffffff he said that he is going to a defence academy...but she kept me telling that i saw him.....i was completely shattered this time...but i thought that i should trust him and wait for him....after 1.5 years when he didn't came back things started getting suspicious ...i decided to ask his friend about him...and then i found out that he never went there and also he is engaged....and now i am dealing with severedepression and anxiety..........somebody please help me😭😭😭😭😭😭😭😭😭😭
