Just needing to vent

Y’all, I’m struggling. I’m the primary breadwinner in my household. I hate my job but can’t change due to kids schedules. Plus I do all the cooking/cleaning/laundry with minimal help from my family (husband, teenagers/medium aged kids). I’m tired. I ask for help and I’m told I’m being dramatic or whatever. I’m just tired of being everything to everyone. If I get sick or whatever, I get told not to be grouchy. I’m just at a loss.
