Struggling

I'm a mama of a 7, almost 4, and 5 month old...i Clean multiple times daily in large amounts. My oldest two have chores now so it does help me out some....but I just am finding it hard to get out of bed in the morning. My period is late and I can't afford to start therapy ...we struggle to pay bills and some don't get paid. It's even harder to get groceries. I just need a break.... I have blood pressure issues and the meds I take have flaws but I can't switch the type of meds until I stop breast feeding.... just a lot of stuff on top of other stuff. And I know that that life but I just need something to give...
