Needing to vent, please read am I wrong? ?

First I'm 32 weeks and have the flu :-(, second thing me and husband have a total of 7 kids. Everytime I try to get a lil rest from being so worn out, I get disturbed by the kids non stop and husband. I'm so tried I feel like I could cry. I don't sleep much at night even when not sick, cause either husband is snoring like a bear or I just can't get comfortable or I'm having to pee every 30 min. But I make sure especially when he is sick to make the kids leave him alone. It's so frustrating and I have said things to him about letting me getting a lil nap but I get the looks or comments of stuff needs to be done. I don't know how I am suppose to get better if I can't even rest a lil bit throughout the day. Usually he is working Monday thur Fri so I try to take that chance when he is home to rest a lil bit but can't. If I don't heyy some rest soon I feel like I'm going to snap.
