Please help before I end up on Dr. Phil!

I have 4 kids. One that belongs to me and 3 step children. Their ages are 5,6,7 and 8. I was a single mom of one for so long and now I feel like because of my husbands schedule i am raising all 4 by myself. I love all my babies but sometimes I get so stressed out that I feel like I am going to end up on the psych ward or having a heart attack. My son knows how to listen and is well behaved but my newely acquired babies where raised soley by their dad and haven't had much structure or proper discipline and are quite wild. They lie, steal and tear up each others things just to be mean. It doesn't seem to matter what I do they never listen. I don't get proper sleep because one of them is always having a nightmare for one reason or the other and I never get to sit down. I am so stressed out! I love my family and leaving them is no option for me, but I need to find a better way to deal with it all. I feel it physically making me sick. I stay tired all the time and constantly sad. I cry for no reason and feel my heart rate speed up drastically. I am now beinging to have panic attacks. Please give me some advice! Am i loosing my mind???

thanks wearyRAsufferer. That means alot to me. I just don't know which way to turn sometimes. I have talked to my husband about it and he says "they are out of control and I'm sorry that your in this situation". Yea thanks... that doesnt help me out at all. Now I am starting worry about my son. my son is starting to act sad all the time and that's the last thing I want. I feel like the worse mom ever right now. I was trying to give my son a family and instead I've taken his joy

Whoa Mama! Your situation is tough. You sound like a strong, smart person though and I'm sure that you will be able to work through this. I too started to experience A/P for the first time when problems arised in my blended family (conflict between my daughter and second husband) Are you able to get some family therapy? Do you have a clergy/priest/rabbi who could provide counseling for you? Whatever you do, please take care of yourself-your health and well being are so important! Take time for YOU-meditate, pray,exercise. The kids should be going back to school soon-Yay!!! Resist the urge to clean, cook and do laundry-just do what helps you to relax and feel good for a while-you deserve it. Then you can get some perspective to make some positive changes in your household. My thoughts and prayers are w/ you!
