I struggle with many of those things as well, I mean I think the ostracism and bullying I faced as a child really took its toll on any self esteem I might have gained. Also I find things in general very frustrating, especially the current state of my mind. Anyways I am not sure if those are necessarily separate issues than depression considering environmental factors can contribute to mental disorders, things like bullying can therefore contribute to things like anxiety and depression as well as related issues.
