I think that a person's change is difficult for others when it effects them - that is not to say one should not change and take care of oneself, just that others (spouse, children etc) are often not happy since the changes also change their life (one does not drop everything to make a snack, one goes and does something that only is interesting to them and partner stays at home - and so forth). So it is uncomfortable for all for awhile and sometimes it works and sometimes it does not. You do need to take care of yourself and I am sorry that your spouse is having a tough time with it and not helping you more.
