Sometimes I wish I could reverse roles with my fiance so he truly understands how much I do... he works full-time and I'm home full-time right now with my daughter.. I love her with everything I have, but there are days I'm so drained... I never have a break.. ever I'm constantly going all day, feeding, changing, playing, doing laundry, dishes, vacuuming, dusting, cooking dinner, cleaning up dinner... taking care of two dogs.. keep track of all my Dr apts and my daughter's as well, and the list goes on. He tells me he COMPLETELY UNDERSTANDS. Well I beg to differ... I'm so tired all of the time my daughter will be two in almost 4 months and has only 8 teeth in so far... it is taking a lot longer for teething then I ever thought.. which makes her extra needy.. I don't blame her I can't even imagine the pain babies go through with this.. but I'm tired.. while he sits at work all day typing on a computer I'm home running around the house like a mad woman. And it's crazy I do so much cleaning yet I feel like the house still looks like a tornado went through it!!!! Just one week to switch roles with him then he will really understand what I do daily compared to what he does daily! Then maybe he'll appreciate me more! Cause I'm tired of feeling unappreciated I do so much and don't ask for much. Yet here I am feeling defeated and shitty.
