Just a vent

I'm 24 weeks with my third and going crazy! I'm on bed rest due to preterm labor and I have two other kids, ages 5years and 19 months. My husband works all day and it's just me an the girls. I feel awful that I can't so much with them. They are bored and running around like animals right now. It's storming so we can't go outside or watch tv (cable goes out when it storms) and I have no family nearby to help. Oh and thanks to bed rest I haven't been able to exercise. I was overweight before pregnancy and I just hit 200 pounds today. This is the first time in my life that I've been in the 200s. I just feel like a shit mom, my kids are stressing me out, I'm alone and I'm a fat ass. I hate this.
