Help! New ways to cope with my stress!

Cassi_Eats_Apples

Basically my life is chaotic right now, I have an 19 month old who is wonderful and sweet and then I have a 6 year old step son whos came to live with us in August as result of his mom getting investigated by CPS for drugs and neglect. This child has had no discipline until living with us, he has ADHD and is to put it bluntly a terror, he argues, he breaks things, he draws on walls, he acts out in school the list goes on. We are doing everything we can and getting help but nothing is changing. In the past I've always tried to "eat my feelings" but I no longer can do that because I find myself getting fatter and fatter and this is my year that I'm making changes. I see a counselor once a week but it doesn't seem to help much, and I've tried Yoga, but its no use I'm still so stressed! What are some healthy ways to cope with stress I can try? Its hard to get time alone because my husband works and someone needs to take care of these two kids, but I need some ideas.
