I'm 20 years old so I am of your age too ans I have experienced it too very badly I use to cut myself, taking pills,sleepless nights and what not but thank God I am all fine now and I fought with it...but when I was in that phase of my life i experienced many things and learnt many things which I thing I should share with you guys and maybe they will help you in getting rid of it..

 

The very important thing which i think is is all we need is someone by us to help us to listen to us what we are feeling and to share our problems with... i was alone too.. so I made so imaginary friends to whom i talk and share my feelings and i know this sounds stupid but i had no other option.. but with you guys this is not the way because now I am here for you all and that's why together we can kill depression and live anew life happily.

If you really need someone to listen to you or to give you some advice  I am here for you guys always you can contact me(addu.rehman7@gmail.com) and can share your problems,and i will be replying your comments too and we will sort things out together.
