Don't know how to deal with biting toddler! Help

[Emonade]

15 month old DS, was late getting teeth, now has eight, he has just started having tantrums/big feelings, and with this has come really really biting me, to the point I've had blood blisters/bruises/broken skin. What do I do?! It definitely isn’t teething and is just I am cross. I am also currently so tired and haven’t had a break any time for me in about a month so am feeling extra sensitive and the biting seems even worse and I feel like the worlds worst mum at the minute too, I am full time SAHM currently.

I’m not sure I can be too much help, as I didn’t love this solution but it worked - my son was becoming a biter at about the same age, maybe closer to 18 months, and I tried to do a firm “no” and moving him away from me - didn’t work. After a couple of months of this not working my husband properly shouted “no” at him. Caused tears, but after two or three incidents of being shouted at he completely stopped biting
