I agree with this subject too! I've had days where I'm waiting for extra hands to appear to clean the house and the big answer book to fall out of the sky so it can at least answer why we get chronically sick and how we keep the backbone to walk tall and smile. I'm not sure if this will help you cope, but I have a cat who acts more human than cat. Even tho I am allergic to him I still get the biggest enjoyment and love from him than any other cat I have owned. His name is Duncan (Scottish pride) and he will let you know when it is petting time and what you were doing was not as important anyway. He lets me hold him like you do a baby over my left shoulder and my husband can hold him like mr. bigglesworth from austin powers. He'll drag his yellow feather on a stick around like a baby and can only put it on something else otherwise he looks at you and meows like "where do I put it now?" He crows at you when you come home until you pick him up. Then he'll race around like something shoved a rocket up his butt because he has to or just went to the bathroom. He is the funniest thing and the sweetest thing in the world. I know that if you get a cat like him that he will distract you enough from feeling like the tons of weight is getting to be too much. I'm sorry if this doesn't help, but to be honest I've been dealing with this since I was 15 and now at 24 I can't remember a time without fibro, heartburn, migraines, arthritic hands and feet, IBS and so on. Plus my dad has a slight handicap and has helped raise me to believe that you can do anything you set your mind to until your handicap puts a stop to one or two things. I think it would also help you if you tried to look at it as I have limitations and there seem to be more. So let's reevaluate what you want out of life. For me I want to be a casual girl who doesn't always get fancied up to do groceries, an easy job, and at least one child because I don't know if I can give two as much care and attention (cuz I'll never run outta love) as I could with one baby. My husband helps, but he doesn't have boobs.
Bottomline I, myself, couldn't tell you the ultimate answer to when is enough enough. But I think that looking at things in a simple light helps you deal with the tons of weight and relax. My husband's always telling me that I can't sit here and get myself excited because my pains will not totally go away, because getting upset all the time is counterproductive. I hope you feel better than now really soon!!!
