I feel like the reason I still feel pp depression is because I’m trying so hard to be the best provider I can be, and some how I still feel like I am not close to it. I wake up at 4:30am for work get back home at 4 pm and I’m still broke all the time. I wanted to invest Im getting certified for eyelash extensions in hopes to bringing more income that way, but if i do pay the 500$ for a 4 hour class I’ll be completely broke and my daughters birthday is coming up.
