Yes Yes Yes!  When we are taught we are worthless, we learn to practice it, and it's very hard to break that mindset and habit, even with God's help.  I talk with God a lot about this, and with other people who love me.  I have to practice loving myself, but in my willingness to keep moving in that direction, I see positive changes, though very slowly.  I don't quit trying and seeking God's help, and am grateful that I have a lot more self-esteem than I used to.
