Some skills can be learnt later in life, it is not all lost.

(Due to childhood neglect, I was misdiagnosed with autism as a child -I didn't learn what I had to when I had to-. Nevertheless, last summer I did some voluntary work with a research team at a psychiatric hospital, the article I wrote may be published. It's a small step, but it is something. Sometimes what seems to be impossible ends up being possible years later)

It's difficult to help others while you are not feeling well enough, but you can take small steps that eventually lead you to what you want, even if right now you can't directly go for it.

(I lost a whole college year due to CPTSD, depression, psychosis, ... and haven't made a friend there yet..... but I get along with some professors, which is enough for my future...)
