I used to have trust issues because of my sperm donor. He left me with a truckload of guilt trips, fear and trust issues. At this late date, I'm still working through them although I've come to know that (God) my Heavenly Father is the Perfect Father.
However, the sperm donor wasn't the only one that messed up my mind. Seems the family system was messed up all the way around. I learned early on that if I was going to be taken care of, I'd have to do it myself. Throughout my life I have found that I ask God to "fix it" but have a really hard time letting go of the thing that needs fixed. It takes time and practice to build up the Faith to trust Him. Each time I have had Faith and trusted Him, He's come through for me. He's always been faithful to His promises.
