unfortunately only you know what it means to know how to help yourself but not doing so.

for me when I know what I need to do and am not doing it, it usually means I am too focused on someone else to take time out to do what I must do for myself...

the other day I was more focused on what my children and my wife needed rather than taking care of my own needs.

For me another thing this situation can mean is that I just dont have the time to do that "something" I should be doing for myself.

during 4th of july weekend I was so busy getting things done. I can remember telling myself I need to go take my medications, dont forget to take my meds, oh my gosh I really need to take my meds ....but I just didnt have will to stop what I was doing for just a few minutes that it takes to take my meds that week end.

Another reason for me this situation can happen is from pure being lazy. Sometimes I just dont want to get up off the sofa and take a shower, go out for a walk, eat healthy and all those other things that are essential to my mental and physical wellbeing.

again only you can say what it means for you to know what to do but yet not do it.
