Loneliness is killing me from inside day by day.please help.i would appreciate it !

ok..so i'm just a regular guy ..20 years old..i am studying in college...the issue that I am facing since a long time is loneliness. Let me put it this way, I used to have quite a happy life 2 years back. Everything was just perfect. I scored good in studies,had a good friend circle,i had a girlfriend whom I loved with all my heart, I used to have a happy life. But then suddenly, my life shattered all the way 2 years back when my girlfriend dumped me..i guess for another dude. Guys i'm telling ya honestly I loved her truly more than u guys could ever imagine..like literally. and everything just shattered. obviously I tried to get her back, but it was all in vain. since then my whole life changed. I changed..from happy to sad,from joyful to full of sorrow..i used to cry a lot..for hours sometimes !! asking god what I did wrong ever ?..i helped everyone, I respected my ex,cared for her,valued her the most..but I never got an answer from god..how could I get ?..Then obviously..time passed , after one and a half year of suffering and pain..i got back on my feet..i became strong..now I barely cry..even when I do.. tears won't come out of my eyes..sometimes I wonder they have dried..heh ?..the only issue that left was loneliness..it's killing me from inside since my break up..and it still does. I tried going out with some other girl.. but u know I could never trust anyone after my break up..nor I can love anyone again with that passion..plus the memories of my ex keep on haunting me when I try to sleep..so going out with any other girl never worked out till now....i got friends..but u know I can't call anyone my real friend. u know I can't share my feelings with anyone..coz they won't understand. I always have to wear like a fake smiling mask in front of them. now I just don't know for how long I could bear this loneliness...i barely feel anything now like totally numb nowadays..like I don't have a reason to live..yet I have to live for my parents..and I am strictly against suicide..i am trying my best to be strong but sometimes I just break down...:/ :(

Thanx a lot to those who read it. u know I couldn't share it with anyone else but here..

Stay strong do not let any thing take up you down.good things happen to who are patient.

I personally believe maybe you should try as hard as you can, no matter how hard it is, to forget about your ex. Maybe you aren't getting an answers from God, because this is your chance to determine something new for yourself, to decide how this will play out. Maybe you and your ex broke up for a reason, because God is going to show you somebody who will mean even more to you than your ex, and that relationship may last. God may be pointing you in the right direction by her breaking up with you, and it's up to yourself to make your path.

If that makes sense.
Either way though, I hope your question is/ gets answered and best of luck to you :)
