Hi,
Your assessment of yourself regarding the degree of outism seems correct.
I have the same problems you have on occasion and always suspected I have a degree of outism and probably a Aspergers as well.
I have been depressed for a period in the past and pulled myself out of it without any medicines.
I also think that the reliance on drugs, slogans and therapist, especially badly qualified ones who are only in it to make a profit is excessive.
