Hard Time

I've had a hard time lately dealing with my emotions. My dad is in the hospital recovering from his bypass surgery. He has some nasty wounds as a result a 24 inch cut on his leg and a 18 inch cut on his arm. He walked today..so that's good. I'm so thankful he came threw it ok. It's a emotional time for my family. I need someone to lean on. I've been super moody lately, angry, sad, emotional.. What's wrong with me?? How do I get this in check??
