Your daughter for some reason has lived her life trying to please everyone else, and not herself. She should seek therapy to find out why she feels she just can't do anything well enough, and is a disappointment even with all her accomplishments. Her many accomplishments I'm sure masked what what really going on with her. I would suggest she seek therapy for this.
Message me, provide more detail on her emotioonal stability.
she perhaps is bipolar, rather than depressed or OCD, MPD, etc.
being bipolar is very stressful, causing occasional depression to linger while having the mood swings.
hope that little bit helps, but i would need more detail to help you more!
I am 23 now and have felt that way since i was very young. i was diagnosed with bipolar disorder and the medication i was given made me feel great, like i was really alive. I think the same thing would work for her. Some sort of combination of an antidepressant and a mood stabilizer.
Wow. That's a very long time for your daughter to have hidden this from you. Did you never notice these "dark days?"
You don't tell us what her symptoms are, so we can't even take a guess as to what the problem might be, aside from her telling you she feels like a "disappointment to others."
But even if we could give you some opinions, that is all they would be. We are not doctors on this forum and only her doctor can diagnose what her problem is.
That she has been able to function well and become very successful, is, to me, a good sign, but since she is still experiencing these episodes, she needs to be evaluated.
I'd say she has suffered with this long enough.
Please let us know what the doctor says. His diagnosis could help someone else on this forum.
I wish your daughter the very best.
Peace
