Hi BrownHat
Yes, I'd absolutely go with separating those thoughts from depression and challenging them

Remember the issue isn't with
you, with who
you are.........the issue is with depression.........and those thoughts are straight from the mouth of depression..........and as with the words of a bully that
does not need to make them true..........they're just designed to try and make you feel bad, to doubt yourself

But you are still
you inside
despite all of the words/thoughts it's throwing at you........
And you know that depression can have you picking faults with yourself and blanking out the good things about yourself...........if you've tried to help someone and it hasn't worked, then that's maybe
all you're going to see (in yourself!!), but why not twist it as in YOU'VE TRIED!!! Now THAT says
so much positive about you........and believe me, I'm sure there would be plenty of people who may
not have tried in that situation, so KUDOS!!!
And hopefully if you keep trying it might work..........it can sometimes be real hard to give some people exactly what they need/or know exactly what to say/might help with
or without depression, but you're
trying.......so that is brilliant!!! Give yourself
real praise, and another tick in that self affirmation box!! And there's just
one thing for now, maybe you can think of more..........to repeat, repeat, repeat!!!
But besides sometimes, people might reflect later on some of the things you've said in trying to help, and it may help them then, so sometimes hard to know exactly how much you've
truly helped!!!
And back to CBT

, who's to say that some of those people not wanting your help aren't just generally having a "bad day", or something might have happened making them less likely to want to talk/listen........it
doesn't have to be about
you 
And you might be giving them lots of what they need in other ways e.g. someone some of them can openly open up to and vent.........but then even a negative reaction from someone teaches you more about what they want/need from you.........and
sometimes that may
actually be just for you to
be around/to be
you and let them work through things their way.......and that way you
are benefiting them
immeasurably in itself.
But try not to let depression pull you away from the important people in your life, I know it can be bad enough
anyway (!!) but it
does not deserve to do that!!!
