My stepfather has been in the hospital this week and I haven't called him. I feel kind of ashamed and awkward about it. 
Why, did you hesitate in the first place?
To be honest, I don't really like him. It hasn't been a very good marriage with my mom. 
I see than, I could tell you that you should just overcome yourself and do it, but its you own personal business...
Thanks, I probably will call. I do feel embarrassed because I know it is the right thing to do.
