Advice on potty training

OMG!!!!! I’m starting to potty train my son. I haven’t did this whole potty training thing in 9 years exact. My 9 year old girl was trained quickly. My son lawd...I’m having a hard time with him. I’m trying to have patience with him. Today he made me so upset...he pissed all over the bedroom floor. I made him go to time out so I could cool off he fell asleep. I feel so bad😭. I don’t punish him always...he has his moments where he does great and yes I praise him for it. But today he showed out...

HELP ME PLEASE SOMEONE UGH 😑
