Frustration

I am having the hardest time logging in food and exercise everyday. I am retired, but it seems like I am busier now than when I was raising 3 kids and working full time. I am very frustrated and feel self-imposed pressure and guilt if I don't do it. This is really nerve-wracking because when I do the exercise, I feel so much better but my brain is so active trying to figure out how to fit everything I need to do after I get done that SP just evaporates. So what should I do? I don't want to go back 3 weeks or something like that and log in all the exercise; it will take me forever. So should I just make myself a sign to remember, and try to do it that way, or just forget it or what? It also makes me mad at myself that I can't figure this out, because, from what I gather, logging in all one's efforts on SP is rather important and I feel I should be able to do it out of habit by now. So I need help and suggestions on how to remember to do it, take the time to sit down and do it, and what to do about the big backlog I have of days that aren't accounted for. Gosh I sound like I have OCD! Maybe I do! Help! Thank you in advance, anniepc1
