Some decisions take strength. You have that strength. Hold on to it. You are worth it.
Ask for what you want. If you do not get what you want you can make decisions and choices that are good for you and that you can live with.
Decisions and choices you make one day may be different than the decisions and choices you would make any other day. they are all good as long as they are part of taking care of you.
And, BTW, I am going write what your Grandma said in my heart and remember it for any future day when I might need it!
