Most Helpful Girl
This is not going to be the answer you want to hear, but no one can fix what you're going through but you. Loving someone that doesn't love you back sucks, no matter what your age is. Being young (under 18?) probably makes it worse. You will get over her and years down the rode you'll look back and have a different perspective about the whole thing!
Drugs and alcohol are depressants and only make reality feel worse after the buzz is gone. It's adding an addiction and making you feel more out of control than before. That's just adding fuel to the fire.
There isn't a person alive who doesn't wish they could flip a switch and the pain and thoughts would be gone...but there isn't one. So here's where you have to put in some work. When the thoughts of her get in your thoughts you have to redirect your thoughts onto something else. We have a tendency to ruminate and wallow in the thoughts that cause us pain. We want to think about it without it hurting. Truly, it's hard as hell to shut those thoughts off, but only you can do that.
Use this time to improve the direction your life s going and be ready for someone else who will value your love.
Take care and know that it will get better!
