You had reached your worst today. You realize that you never been like this before right? Yea it cant be denied that losing a friend is harder than break up but you need to know that times heal everything. And everyone deserves a second chance. But still everyone had their own choice. Dont overdo anything after this. Stay calm and keep low. Its okay you dont need to interact with a lot of people. Also, lesson learned that never put your trust on anyone. Never. Repeated,never. Dont be stupid! Isnt what happened before didn't teach you a lesson?
Be cool and be matured. Learn to control your feelings. Its okay just believe thay the chances will come one day. It will never be wronged to be nice w people and to keep trying again and again.
Bcs if you can't start over just dont give up. Remember that!
