I think this is great advice you got and you are so blessed to be getting such good advice. I personally used to live like this everyday for a while in my m and when the bomb dropped and my world seemed to fall apart . I realized thru much trial and error that this was no way to live worrying sooooooooooo much when he was going to let me down again and just waiting for it instead of me geting my hands dirty and putting forth change and getting involved. When you are feeling like this you feel like you are worrying about the R when in essence you are not doing a damn thing to help it you are stalled and living in fear and not participating,, Trust me I did this for far too long. It got me nowhere and never helped/allowed my H to feel loved or cherished.Imagine how they must feel if they feel like all they do is let you down and give you no joy just pain and worry?
There was simply no joy, I was scared all the time and could not enjoy what was right in front of me.
.... when you let go off all ( or as much as you possibly can) of that fear it feels so freeing and it feels good to be alive. Take your time as this will not happen overnite,, just work on you little by little and not only will you change, but the World around you as well.
Best wishes to you on your Journey to find yourself and growing and become a better human being.
God bless...
