Advice on Two Year Old

My son turned two in April and these last few months he’s been crazy. He wakes up too early, refuses to nap and gets very moody and has a lot of crying fits (I can tell he’s very tired)

I put him in his room everyday for a nap. He will just play with toys or scream for two hours refusing to nap. Lately he won’t stay in his room for nap or “quiet time” and cry’s and screams hysterically. If I skip the nap he cry’s and screams for any little thing wrong. He gets time outside to play, arts time and down time to play with blocks and stuff. Any advice to help with him not sleeping? He’s started getting up around 6 instead of his usual 9 since he can open his door himself. He goes to bed around 8-830.

He also takes his diaper off and plays in his poop. We are trying to potty train but he often refuses to go. He’s learned how to get out of his pjs backwards so as soon as he goes to his room for nap he strips naked and poops. Advice? I’m stressed to the max😔 I can’t accomplish anything. He throws fits all day or gets manic and makes messes.
