First, sending some sympathy and solidarity your way.
Secondly, a question - if your baby will sleep for 1 hour stretches then why are you only getting 2 hours in 24?
I don't mean that in a mean way, but in terms of identifying the actual issues. I did a year of hourly (+) wake ups with bottle refusing baby breastfeeding to sleep so I get the difficulty delegating, but even I got more than that, in dribs and drabs. Probably about 4 hours in chunks on 45m. You also can nap in the day potentially (sadly I was back at work when the hourly wake ups kicked in). Grab sleep whenever you can.
Which makes me think it's not JUST frequent waking. Does it take you a long time to go back? At you watching the clock thinking there's no point going back to sleep too be disturbed again shortly? Anxiety stopping you sleeping? Baby that will only sleep on you which means you have to stay awake.
The thing is, if it's one of the above then your baby sleeping longer won't actually help, so it's really important to identify the reason. There are things that sometimes can be done to improve sleep, once the reason is identified.
Ps: I have had 2 hours or less for a short while for other reasons. It's not sustainable or safe in my experience.
