My joints are on fire and I am exhausted

My soon to be 3 year old has been driving me insane lately. He does not want to nap and does not sleep until 11 pm sometimes!! I spend the day playing with him, chasing after him, trying to engage in activities with him, feed him, potty training, bath, cleaning up his toys etc. and by the time I get to sleep I am so tired that I literally just pass out. I tried asking husband to help but all he does is either lie down on the bed and calling out his sons name OR sitting down with him until I’m done doing whatever I was occupied with and leaves. He helps me with laundry and taking out the garbage but I feel like I have to do everything else by myself. I am SO TIRED that I feel like I want to die.
