I'm so depressed rn... I wouldn't let my 3 month old go to my moms trailer where she has openly talked about battling bed bugs & lice for years, they deal drugs, smoke cigarettes and have strangers going in and out of the house. Her feelings are hurt and she won't speak to me. My husband is at "work" in Florida living life like a single man. I haven't had a day to myself since my son was born because he's strictly breastfed & my milk doesn't last very long because my lipase enzyme makes the fat in my milk randomly go bad fast. I wouldn't know how much formula to give him if I started him on that anyway. I'm trying to run a company... I'm behind on bills and taxes... And I spend all my money on a house that we're renting because I didn't want to settle for less when bringing my first son into the world. I haven't been working out. I'm staying with my G-ma who raised me but is showing the beginning stages of Alzheimer's. I just feel like I'm setting myself up for failure and idk how I ended up like this! My son is the highlight of my life... But I just need a small break... And things to look forward to.
