I lost my soul mate, who was also my very best friend.
How does losing your soul mate make you feel?
I'm still young and seeing many people at the moment as I don't want to feel lonely.
You are still young and they might not have been your soul mate, but you should try to not abandon your friends. Perhaps open a line of dialogue and see if there is a way that the two of you can reconnect. I'd suggest setting appropriate boundaries with this person moving forward.
Friends are overrated, I don't need to be with them.
I thought you didn't want to be lonely, so think it's a good idea to give your friends another chance and not leave them behind. You might find one of them to be another potential soul mate!
