I know it’s very difficult.
But having one or two close friends is important. Are you close to anyone in your friend circle or family?
I agree with what you have experienced. The truth is, no one is truly ours except our parents. Friends come and go. Take your experience as a lesson for the future and trust few. Friends are a part of our life, but not the entirety of our life
Yes, friends and partners and love interests whatever have you. They'll come and go. They're not the end of you.
