It may not seem easy to get over somebody but there is ways. my way is this.
1.Tell her you're never gonna see her again, ignore her phone calls, ignore her texts. Just blow it off, if you still have feelings for her how in the world can you be friends with her and plus if she lingers around so will your feelings. you may not ever see her again but if you do this then maybe the next time you see her you wont have any more feelings.
2. Hit up some of your friends tell them about your problems and roll up a blunt and face it. (if you smoke) And if you dont smoke replace this step with something more appropriate for you. People on here are saying to take pills and drink your sorrows away well im saying to smoke them away. It is much safer and you will be able to think your problems through. Not let them take over like liquor can do lol.
3. You'll be feeling fine after this and be able to get on with your life.
AND LASTLY STAY POSITIVE, THERES WAY TOO MANY GIRLS OUT THERE TO BE TRIPPIN OVER ONE!!
