Feeling overwhelmed

I'm on 4months pregnant but I have been doing this for years I thought it would change once I gave him the baby he asked for. I get up and work at 6 a.m every day sometimes at 5 a.m for the past 4 years. I come home cook clean just feel overwhelmed with doing everything with a husband. I'm always hungry and always tired so I dont feel like cooking every day or cleaning but I'm stuck doing it cause I have NO CHOICE I ALSO HAVE AN 8 YEAR OLD SON. Sometimes i have craving for things we dont have but my money is where it should be cause i pay half the rent, then I'm paying cable, lightbill, and car insurance for all 3 cars. I feel really down and alone it's so hard to hold it together and not get upset with my husband I feel he should at least feed our daughter growing inside of me. JUST VENTING 😢😫😫😭
