There are homoeopathic treatment based on your symptoms which can make you feel better, along with counselling. Although some management can also help you in this.
1- remove all the things related to her around you.
2- try avoid to go that places you used to visit with her.
3- always engage yourself in some work never ever give your brain time to think about her.
4- talk with your friends (especially girls) about this problem and ask them to support you by never talking about her with you.
5- do 20 min meditation and 20 min walk in the early morning in nearby park.
6- eat healthy and do not use your bed other than for sleeping.
7- do not watch any type of love or emotional movie, video, or listen songs like that.
8- always watch comedy shows, movies, whenever have free time.

See, don't focus on" I have to forget her" Because energy goes there. More you try about forgetting; more you will remember. Instead focus on what you want to become" Happy, Fresh, Energetic isn't it.
So, focus on that with great conviction.
Follow some basic tips.
?Accept the reality:
This is the most difficult stage. Mind will not accept the reality easily but, you have to do it. Stop becoming victim. Accept the reality and stop self destruction. You don't need to prove anything to anybody. Understand this and prepare your mind set. ?Now stop having self pity and make your life interesting. And surely for that you don't require your ex. You are the only one who can make it. Do following things:
1. Meet up your friends talk to them, share our feelings and enjoy their company as we used to do when we were young. You will feel free. 2. Meet parents, if possible talk to them take their blessings. It works really. Surrender yourself with all your problems and fears, happy and sad moments to them and god or any supreme power you believe in. Surrendering is the most important thing in this process. It helps in letting go the emotional blockages you have.
3. Stop contacting your ex (of course). Always remember She was past and past is passed. Remove her number also from the personal diary and mind. Stop stalking him/her.
4. Have a faith that, you can do it. Do your sadhana (the worship and work) daily. This helps in increasing confidence in yourself. Make a commitment to yourself with a conviction about your sadhana.
5. Hit Gym and get physically fit. See, mind is subtle part of body. If you are healthy, and it will be strong enough to handle this stuff.
6. Play. Enjoy your life. It only come once. Trust me, you start living your life and you will find the way. It changes the state of mind. 7. Try you to pick a hobby which you wanted to do but you didn't. (eg. Music, Trekking, any Sport etc)
In short get busy and stop living lonely.
With consistent efforts, you will make it.
Don't do it just by thinking that" I am doing this for forget her"; do this because you love yourself and there are so many people who loves you. You are surrounded with the plenty of friends, relatives and other human beings. If one person is not loving you, it doesn't makes any difference. Understand this basic and move on.
Your love was not just reciprocated friend, and nothing else. When you will live your life positively, you will be surrounded with positive people and eventually you will meet a sweet person who will reciprocate your love more than you have ever given and more than you can imagine.
You will get out of it slowly over the period of time for sure.
And high time you start focusing in your studies.
All the very best.
