Siddo, I consider you my friend, and I hope you can view this after this message.
Siddo, you resigned less than 2 weeks weeks ago. You resigned completely, including your advisor rank.
I'll be frank here in that coming back and applying in all honesty for a lead admin position comes off with hubris.
As someone who has suffered from mental health, 2 weeks is nothing when it comes to fixing or even lessening them. Not every mental health situation or experience is the same, and I don't know yours but i hope you can explain what has changed other than a lead admin position being opened since you resigned.
Honestly, I will be giving this application a soft -1 the reasons for you coming back are not the right reasons honestly, and they come off as opportunistic rather than as a want to better the community. I can understand wanting to help, but to do it only because a lead position may be open and to honestly go and apply for it directly is just not it in my opinion.
You've been kinda fast tracked once before now, got burnt out, what's the difference, and how would you explain it to the other candidates who see this application and see the resignation, that know you said it yourself hit a wall and couldn't do it, just to come and apply with this hubris.
