You probably have some stress,and maybe other things got in the way of you and your friends. Don't change completely for your friends,find someone who you can get along with.I know its hard meeting new ones,believe me,I've been moving from place to place,away from my friends,and I've had to make new ones.Just try and throw yourself out there. I hope this helps. good luck, :)
Those aren't friends. Trust me real friends stay with you when you need them. Those aren't friends. Trust me I have a friend that's going through this too..she scared me to death the other day bc she tried to kill herself. She is in the hospital right now for a week so far. She is almost back to normal but I beg you not to do the same. God gave you a life for a reason. If you don't believe in religion than find other help like from a consueler. Good luck
If you have one friend that you trust is a true friend, go talk to them. That is better than 100 friends who are just casual. True friends are forever, you may lose contact with them for 20 or 30 years but you will keep them in your heart.
