How do you know when to end a friendship with someone? I'm now officially the worst friend ever and I can't take much more.
Why are you the "worst friend ever" ? If "someone" doesn't appreciate your friendship, just do him a favor; distance yourself from him.
Well... I don't know your situation. However. A best friend of mine has sometimes told me that he feels like a horrible friend. So what should I do? It may be true, I don't really know, but I know that in any case, I appreciate his friendship. Nothing will change that. If you feel that you are the worst friend ever; tell your friend, and see what they think.
The worst friend ever? How so? Plus, if you feel like that, you're still in a position to mend the friendship. Stay strong!
