Custody of my boyfriend's kids and misscarriage

I suffer from anxiety and I feel like I'm going into a state of depression and have no one to really talk to about it. I hate my job so I'm in the process of finding a new one. The company that bought my job out is full of crap. I had a misscarriage while at work. And in the midst of all of that we gained custody my boyfriend's 2 kids. Boy (9) and girl (7). Our son is pretty ok he doesn't try us as much but he is over weight and not as active as he should be. He wants to play the game and lay in bed all day and we have gone to the zoo and six flags so far since having them he has to sit down every bench he sees. Our daughter she is very sneaky and lies so much. We have cameras (we had them before they moved with us) but it's like she knows they're there and she doesn't care. We try to find different ways to discipline other than a beating because of how they were treated at their grandmother's house. I feel like I'm a little overwhelmed being that I work all the time different schedules and I'm not able to be there at night. I'm not complaint because I love those kids like I birthed them but it's only been a month having them and I really want it to get better. I don't need any negative comments I need words of encouragement and if any one has gone through or going through something simular.
