Sorry for the long post

Backstory 

Graduating college had a 3.6 gpa which isnt bad. I graduated with a degree in accounting. Did 2 internships hated it. I wanted to work hard and build something. 

In comes my father an euntrprenuer with small businesses and an offer that a dumb graduating college senior decided to accept. In 2014 i took an offer to be a cashier at one of his businesses at 10 dollars an hour and learn the business from the ground up. 

1 year later i am closing night manager at 12 an hour. Another year i am making 35k a year closing nights. Last 2 years i have been general manager at the store opening and making all financial decisions making 56k base plus overtime. Averaging 70k a year ( 55-60 hours a week).

Also asked for a raise because i wss able to raise yearly sales at my location over 700k/yr and was denied. 

June 1st 2018 - i quit. Sick of working all holidays, no benefits at all and always a promise of my own business as they sell slower locations and buy new businesses. Hated the expensive city i lived in (boston) 

I quit with no plan because i would never attend interviews since i had my good paying job also looking into moving to either providence or atlants Georgia. now i am trying to figure out what to do. 

I have my fiance and 2 kids who depend on me. I have been doing odd jobs while i figure it out and we have been living off our savings. Going to start uber until i figure out what to do. 

What should i do? I was thinking of going back to school for my masters since i did enjoy accounting and now that im a father i will just have to deal with the boring office life until i am able to fix and flip. 

Or what type of jobs should i apply for with small business management skills, i managed a team of 10-15. 

I am currently a landlord and hate it so want to try flipping but need to get my income organized and savings higher. I act normal to my family but am worried

Looking for advice and sorry for ranting.
