HELP😩

My baby is teething badly, and fighting naps. He seems to be running a slight fever and has been whining all morning! I'm going crazy. I left him in his crib for a half hour and took a shower and did things cuz I can't stand the crying. I thought he'd end up falling asleep but still hasn't. He's obviously over tired now, as he's been awake since 730am and it is almost 1pm!!! I'm going nuts. I gave him Tylenol but idk what else to do 😭😭😭
