So S14 is giving you a hard time. Take it from me - you're just getting started so be strong. It was my experience that teen boys are a piece of cake compared to raising a teen girl, especially one you're raising on her own. UGH! Ashley was 100 times more difficult than Brandon. And even at almost 21 - she still pushes my buttons and gives me grief at times. Though I can honestly say today that I'm seeing the light at the end of the tunnel.
Back to school is always a good thing. Routine. New plans. Goals. Fresh starts.
You ARE a survivor now. Now it is up to you to create the life you really want. Figure it out. Do Overs can be a blessing.
