Hi and welcome to Teenhelp. Leaving a person that we find very close to our hearts is tough but you said you were coping. You are only 16 so you have a long life ahead of you so don't kill yourself over it. You will find someone else even if you don't know it yet.
I reckon the best thing that you can do to get over your depression is to move on from him as that will make you feel better. I am here to talk to you at any time so just message me whenever things get tough.
Please take care, I am here for you
