First of all, sorry for my bad english (not my first language).
I've recently begun thinking about this. Don't know why it has'nt occured to me earlier in my life. But the common symtoms of depression you can read about, like: feeling hoplessness, feeling pessimistic, low energy/tired, feelings of worthlessness, troubles with thinking/concentration, thinking alot about death and so on is a description of my personality. I've been this way for as long as I can remember (probably 4 years old or something like that).
I've been diagnosed with clinical depression/relapsing depression a number of times in my adult life. (I have not had an evaluation for autism/adhd). Those times I have been really feeling low and sought out help, but the symtoms have never gone away, I've just felt a little bit less bad for a period of time.
I don't know what I want with this post, maybe just share my thoughts cause there is noone to share them with in real life.
