I understand your train of thought here and how it's scary. I have been there and know that it can be very daunting to think about but I offer this, keep in mind these are only thoughts and none of it based on reality itself. That is yes, it is tru you're not guaranteed to have people love you but that does not in any way make it true that you WON'T find friends again. If the possibility exists of one thing then the possibility for the other exists also. So in thinking about that, try not to 'what if' your way into further depression but focus on the other possibilities in life. More than likely, based on how life usually works, you'll find more friends. I'm not making a guarantee but just saying that possibility exists too.
