12 week sleep regression?

My son used to sleep 10 hours in a row at night but is now waking every 1-2 hours. I know there’s a 4 month sleep regression but this is a little early? He’s 14 weeks now and it’s still happening..... Has this happened to anyone else? Are you starting to go a little mad? Has anyone made it through to the other side and is still alive? Is that even possible?!
