Soooo tired

I am just so tired and need to vent. My little guy had his bottom teeth finally cut through after months of waking 3-4 times a night, and for a couple weeks he fiiiiinaaallly slept completely through the night. But now the past few days he's doing the same thing and wakes up every 2-3 hours and it is so exhausting!!! Will it ever end??!!! Does anyone have any teething advice? I'm still EBF and I'll usually try to feed him when he wakes up- is it bad to comfort feed at his age? He's 9 1/2 months.
