Have I Lost My Mind?

Ok I am married to a wonderful man who helps as much as he can..he goes to school fulltime and is working towards a degree in web graphic and design so that he can support us...that is his job right now on top of taking care of the bills, repairs in the home and he also does many on the side jobs....my job is to take care of our son, cook and clean the house....he helps out with our son when he can....he doesnt demand the house be clean or that I cook gourmet meals....we are both very busy doing very different things....I have a wonderful sister that offers to give me a break at least once a month and keep our son for a night...and with the holidays and sicknesses it has been like 2 months since I had an all night break and one part of me feels guilty for feeling like I need to get away I mean I dont have it bad at all what should I need a break for...and then the other part of me wants to leave my son with his father check into a hotel/jacuzzi suit room for a few days and do nothing but relax...and there is an even huger part of me that feels guilty for feeling that way at all and then I freak out and feel like mayby I am incapable of being a good mom because what good mom wants to run and hide in a hotel room for a few days? And then I get frustrated and tell my husband how I just need a break from doing everything and I am burnt out from doing everything and then he gets all upset because he thinks that I think he isnt doing anything if I feel like I am doing everything...and that is not it..I dont know how to tell my husband how I am feeling without making him feel like he has to do more...I look at his load and look at my load and wonder "what the hell am I complaining about" and then to top it off I don't really know anyone else that has any kids that are my sons age that stay at home....so a lot of the time I feel like I am rotting away in the house and it gets so old doing the same thing over and over everyday....and I guess part of my problem is that I need help learning how to keep my son entertained keep the house clean get meals prepared everyday and still have time to look nice for my husband and keep our relationship strong, wild and romantic and have time for myself...its like I have lost myself...what I want to know is what mother has been able to do all of this and stay sain? what mother has been able to do all of this and keep time for herself? what have mothers done to keep themselves from feeling this way? am I the only one that feels this way? is it normal? and how do you single moms or moms that carry fulltime jobs do that on top of all the other stuff...you guys probably think I am just a big baby...huh? I mean I know looking at the big picture I have it pretty easy so why doesnt it feel that way?
