>>12937933>I'm a diagnosed autisticThis puts you in good company. You seem to be high functioning enough that I wouldn't sweat a diagnosis. It's not like you're nonverbal and screaming in the corner all day.
>I have severe learning disabilitiesEh? Take up painting.
>I have bad constipation problemsThere's probably a medical solution, have you seen a doctor for it? If not, there's always the more water, more fiber and over the counter stool softener solution.
>I'm constantly miserable.This is the only thing you've said so far that is cause for concern. I don't know how to help you there, just know that it's not uncommon to feel that way. I'd guess that it's not going away on it's own so you probably should make some changes to your daily routine and see if things change. Also, see a doctor. Modern psychology/psychiatry is still pretty shit but meds make a difference for a lot of people. Maybe they'll work for you.
>what is the rational thing to do?Can't really say what death is like. Could be better. Could be worse. If you're young I'd advise against thinking your current state is representative of what the rest of your life will be like. Shit changes, sometimes for the better. In my opinion it's better to stay here and face the demons you know than to fly to ones you know not of.
