Single parents question

I’m a FTM to a 7 month old boy who I absolutely adore. He’s honestly the best! I’m a single mom, dad is not involved at all. I live with my parents and sister, my mom and sister do help with things a lot. Mostly just sitting with him so I can eat, or go to the bathroom. Or get something done around our space.

But I never get a moment to myself. If I’ve asked to do so I’m laughed at because I’m “a mom now” and “moms don’t get time to themselves”.

My son is sick for about the 4th week in a row as we’ve just started day care in January. He didn’t sleep well at all last night (which isn’t unusual for him anyways) so I’m exhausted. He’s too sick to go to day care tomorrow so I have to take off from my new job that I just started 3 weeks ago to stay home with him.

I feel like I’m drowning some days. I just need a few hours to sleep. Or a couple hours to myself to take a breath. But that’s not available. So my question is to other single parents, how are you doing this without going crazy?
