Addicted to food? Depressed, lonely, overwhelmed...help?

What should I do? I am always depressed or on the verge of a meltdown. My mood fluctuates like a seesaw, I eat all the time, graze all day and sometimes eat A LOT at once...I hate to see food wasted so if others in my family aren't going to eat it I will try to. I crave certain foods so much that I'll think about them all the time, look forward to eating them, and will do so alone and hide it from my husband who will just yell at me for it. My husband almost never shows me any kind of affection. The last time I got a voluntary hug from him was when we were dating like 5 or so years ago. The only affection I get is an occasional tap on the lips when he is in a good mood, or the dreaded call he needs every so often. I dread it cuz I hate how I look and how I feel afterwards. I feel like I've been used, and feel very unsatisfied cuz I rarely ever cuz he's done in like a minute or less, no kidding. He's always got something he's ticked at me for. I feel like 90% of the time I am in a daze, I am so forgetful sometimes that it scares me, cuz I have forgotten to do some things that could have endangered someone else. I am so pathetic, I have 3 kids, who I am homeschoooling, they are wonderful kids, (they are only 5,3 &1), but they are kind of undisciplined. They obey about 60% of the time, most of it being outside of the home....and some at home, If I am in a good mood and doing what I should, then they will listen much much more. The 5 year old has mild form of autism, and the 3 year old is very delayed in speech, the 1 year old is fine, but VERY demanding of my time (Still sleeps in bed with me and husband). My house is messy, laundry isn't kept up with. Right now I have about 6 loads of laundry to do and I haven't even started. I feel as if there is no point to most housework because it gets messy almost immediately, and looks even worse than before I started. While I am in one room cleaning, the kids are in another room destroying it...jumping off furniture. When I become aware of what they are doing I stop them and reprimand them. Time outs are daily, but stuff still happens. My husband disagrees with homeschooling and so does his entire side of the family. My side of the family agrees with me homeschooling. In fact my 5, and 3 year old are both progressing. I am inconsistent tho, the schooling is at a dif time every day, routine is almost non existent, and I know my 5 year old needs that consistent daily routine. I do almost no housework all day, anything I do get done either goes un-noticed by my husband or family or is destroyed before they get here. Nobody seems to want to visit me, everyone's always busy, nobody really calls, only my Dad once in a while. I do not have a license, nor a car. We have a truck (was my husband's before we got married), but it seats 5 uncomfortably. He doesn't like it when I drive, he yells and badgers and nags and stresses me out when I drive cuz I don't drive like him and I should apparently know everything. We cannot afford a new vehicle, and I can't even get out of the house to practice driving/ learn or get a license cause I am stuck here. I have a learner's permit. I almost never get time away from my kids, if I do it's like 1 hour or so and interrupted constantly by my husband. We haven't gone on a date in a year or so. i feel like I am holding my 1 year old all day, and I still feed her too. I have no support/no life and nobody even seems to care. What's the freakin' point. The only thing that gets me out of bed in the morning is my kids. I love them so much and I want the best for them, but am frustrated cuz I can't seem to give it to them. I know I wrote a lot here...so maybe you can just pick one issue and give your 2 cents.
