Is AUTHOR wrong in the post ? POST : Context: In college. This happened twice, actually, with slightly different scenarios; I'm the common denominator in both these somewhat unfavorable situations, so I'm concerned about this.

Case 1:
I had a friend, Jeff, who appears to be depressed *as far as I can tell*, although Jeff has never really been to a mental health clinic to have it diagnosed.

Jeff and I mostly talk and support each other at times and I, being good at academics, often help Jeff with his classes. Jeff is not exactly struggling with to pass his classes, but his grades are rather low and he doesn't have much hope for his future.

At some point I decided to cut off the friendship because

1. Jeff does not currently offer much of value to me. We do not really share many similar hobbies or interests, so I don't find talking to Jeff entertaining. I trust Jeff and he is one of the very few people I can be honest with some personal things about, but I do not value that very much.
2. Jeff is a depressing influence. Most of our conversations are about Jeff being worried about his future or reminiscing about his past crushes, which in turn makes me feel depressed. I believe that I may have been a source of confort for Jeff since I'm optimistic in a weird way.
3. As far as I know, I am not capable of changing Jeff's excessively pessimitic behaviour, so I did not expect this situation to improve. (This dynamic lasted for most of a year.)
4. Jeff does not seek other people for help and believes other people to not understand him.

Case 2: Emily is essentially the same, except

1. Instead of worrying about her future, she just has a general (perhaps warranted?) sense of inferiority relative to those around her. They both worry about their romantic pursuits.
2. Emily insists that she's very okay with her life and not unhappy no matter how depressed or pessimistic the things she says sounds.

-----

In both cases, I broke off the friendship by being honest and telling them that they not useful to me and even a negative influence to me in their current state and I am unable to fix their problems, so I cannot expect anything I do for them to be worthwhile in the long term either; being what I believe to be a reasonably self-centered person, I choose to terminate the friendship and avoid talking to them.

In Jeff's case, I blocked him on social media after, but I realized that that probably wasn't necessary when it happened with Emily later on.
