If you are on an emotional rollercoaster,, with swings, particularly to the negative, that is ongoing for weeks then you may be burnt out it close to it
This can cause a loss of perspective. It can also cause impulsive behaviour such as suddenly resigning because you can't cope and want to run away and hide.
I mostly avoid making rash decisions by always waiting a few days and making sure I consistently feel the same way.
You have nothing to lose by contacting HR and asking if it is possible to go back. If they say no, you are no different to now, but they might say yes. Swallow your pride and just ask. Say sorry and you acted impulsively.
But, you need to consider coping strategies to avoid getting in the same position again.
You also should consider how fragile you are at the moment. If you are just down over the job then maybe it is ok.
I think I'm just sad about resigning, even though deep down I know it was the right thing to do.
I'll miss everyone though and kinda regret not having a proper goodbye with the team - I just asked supervisor and manager to say goodbye to them for me
Honestly? Judging by how you have been explaining the job, I think you did do the right thing. It’s perfectly normal to mourn over a change like that, especially if you feel like you didn’t have ample opportunity to say goodbye. When I left my last job I bawled as I walked out even though I said my goodbyes, was going to a better situation, and left on good terms. So it’s totally okay to feel some grief over leaving.
If you want my opinion, I say do not blame your Autism for losing that job. It sounds like some of the blame lies on your old coworkers/bosses as well. Your Autism helps you to see the world in a different light than others, so it’s not fair to blame it as the sole reason you needed to leave.
