Is anyone just tired ALL THE TIME?

I work 3 days a week, school 2 days, and have two toddlers (aged 3 and 1). 3 year old is in preschool and the 1 year old is being watched by my MIL and stepmom (they alternate days).

Even with this much help I just feel exhausted 24/7. 1 year old wakes up hella early like 6am every single day and 3 year old has been having night time wakings again.

I’m just so tired and go through so much caffeine throughout the day only to feel like crap by night time. My fuse is short and I just can’t deal with it. I’ve been expecting it to get better but things are still not good and I’m just tired of feeling this way.
