It'll stop. Mourning is a very personal process. Feel hurt, feel sad, feel angry, feel acceptance. For one it takes days, for another it takes months. It is ok. Be grief-stricken. It is normal.
Never mind those who say, it is time to act normal. It is your own pace.
I am sorry for your loss.
Try to visit a therapist, maybe all you need is to be able to talk to someone who can just listen.
They might also be able to give you medication in case you've become depressed to help get you back to normal.
If not then I would suggest surrounding yourself with things and people that make you happy, do everything you can do distract yourself.
I relate and understand. My bf died on almost a year ago and I still cry as if it were today. Sometimes it happens when I'm out and about and out of no where I start balling, sometimes uncontrollable. Then there are times when I can laugh or smile when I think of the funny/happy/good memories. I knew my bf for 18 yrs. She passed unexpectedly it's been one of the most difficult times of my life. It's been a healing process. Talking to people will sometimes help but the tears won't be as often as they are for you now so stay encouraged. Everyone is different. Heal, grieve in your own pace and time. Sweetie, I'm sorry for your loss. Losing a friend and a bf at that may be one of the hardest things to get over but I pray that you will find comfort and peace as you move forward.
