I really am overwhelmed

I know that being Overwhelmed is an indulgent emotion but I really feel like I have too much going on and I’m not sure what to do about it.

C – I have a “real” job , 2 side gigs, a husband and 3 children
T – My “real” job is really big/I am an executive with a lot of responsibility; my one side gig I could easily grow grow grow but how the hell am I going to do that and my coaching side gig I’m almost afraid to take on other clients because how in the hell will I have the time. I get up at 5:30am and go to bed at 10:30pm and I am never done and I pretty much work nonstop including on the weekends which is when I do a ton of my side gig stuff. I don’t know that I can keep up this pace. I would love my side gigs to be my real gig someday. Problem is my real job pays really, really, really well. I would have to make a LOT of money in my side gig just to match my current salary.
F: Overwhelmed (and exhausted) constantly
A: Spend a lot of time frantic with tight feeling in my chest about never ever getting everything done and dropping balls, have gained weight, not taking care of myself very well
R: I do get most things done but at what cost.

I am not sure how to solve this. I can’t stop my real gig. I am the bread winner for my family with one in college and 2 close behind. I don’t want to stop my side gigs. I would like to spend some time on the weekend not working. I feel like I’m going to get “found out” in my real job, as I do some side gig stuff 9-5, BUT I also work on my real gig every night and every weekend so there’s that. I feel totally stuck.
