A separation?

I never thought this would happen to me, but it has. My parents are going through a separation and it's sucky. It's all on my dad. It seems that my dad is the one who is unfaithful in the relationship in the past and is the one who doesn't love anymore and is the one who wants to quit. I don't know what I can do to help my mom except just take it day by day. My medicine is making me incredibly calm about everything which doesn't help my mom considering she's on the edge. Help us, Obi-Wan Kenobi, you're our only hope.
