Who is responsible for your happiness?

No one but yourself.  Stop blaming your daughter, husband, mother-in-law, or anybody else.  They are distractions you created for yourself so that you are not the one to be blamed.  Tell yourself that your happiness rests solely on your own shoulders because God placed it there, and He does not give more than what He made you capable of handling.

Your daughter feels the burden.  If you truely love her, remove that burden and place it on your own shoulders. Then you will be truely free to follow your own path, which, you will find, may have been the real frightening thing you have been trying to avoid all along.

Being nice and being good are not the same thing. Jesus is good. Is He nice?
