Coaching my sister but I need it too

Hi Brooke, I’m practicing coaching on my sister just by accident because I know the tools you’ve taught me can help her if she chooses to follow through. So here’s the model from her situation- C- Supervsior T- She favors everyone and gives them gifts but me. F- Unapperciated A- Complain, Call my supervisor out on it R- No gifts etc What I explained to her is that she needs to love and appreciate herself and that she’s giving her power away. In doing this, I’ve realized I could use help on this too. What are alternative thoughts to think to love and appreciate yourself? What actions can one take? (I’m thinking for the future in case my mom decides to give my sister gifts but not me). Love your advice! Thank you!
