Bad day, bad mama

I've been having a hard time with the kids the past few days. I am sure it's because it's winter and all, but they have been so full of energy all the time and so loud. I have also had to be dealing with them on my own most of the time because Jason's been sick. Then tonight I finally got out for the first time since Thursday, to the YMCA with my best friend for a little me time, which we then went to Martin's and to pick her daughter up. Her husband tagged along to the Y with us as well although he didn't work out at all with us, and just did his own thing. I get home feeling a little better, but as soon as my friend walked out the door I tried talking to Jason, about nothing in particular and he just snapped at me. Something about me being a cheater. I have been married to this man for more than 6 years now and have never ONCE done anything that could even be considered cheating. Most I've "done" is having old guy friends on my myspace and facebook that I don't even talk to! I am so upset. I don't deserve this crap from him. I haven't done anything wrong. At all. I don't deserve this lack of trust. I am so very tired of taking care of him and the kids all the time, rarely having any time left over for myself(unless I stay up way late, and by then I am exhausted so all I get is a few minutes here on the computer). I can take it anymore. I am working my butt off trying to get this weight off, but even with all the extra excersizing and eating healthy it still doesn't want to come off. I want to de-clutterize my house but every day is spent cleaning up random messes and picking up after everyone else just so my house doesn't look horrible. What would you do? I guess that's a pointless question.... no one will ever read this anyway.....
