Put on a LOT of weight since losing my job....enough is enough?

5'4'' and 195ilbs...obviously overweight. I was 120 my whole life, and then had my second son bringing my weight to 150. Shortly after I lost my job, and sat on unemployment for a year and now i'm 195. I eat a lot, i mean a LOT...I eat when I'm not even hungry. I watch tv a lot and for whatever reason always have to eat when I'm watching it? I feel down in the dumps about my weight, always say i'm going to do something, but then never follow through. Then, when i fail, I just eat more and feel a little more down in the dumps. I have a 2 year old and 3 year old. I would like to say that I get enough exercise chasing them around all day but obviously not. Since they are so young though I don't like going out with them by myself. I also live 40 minutes away from the "closest" gym. not very convenient! I need to get my life back. I currently own 2 pants, 5 shirts and won't buy more because seeing the size 16 depresses me or the XL/XXL shirt. I'm looking for a DETAILED plan, obviously i'm not capable of doing this on my own or I would have already. Interested in a detailed diet plan, one that will show immediate results that will give me the motivation to continue. also some idea on exercise that I can do. I'm VERY out of shape, very lazy now i've had zero motivation since I've lost my job. I know that I can't go from 200lbs to 120 in a month, I just need something to start me off. Also, how do i stop eating ALL the time?
