Scared...Mad

I called my mom last night...she was totally out of it. Rambling, giggling, didnt know what she was talking about. Just sounded really bouncy and out of it. Then she started complaining about mouth sores or Ulcers...I think she is doing drugs. But I dont know. If anyone know what mouth sores are caused from? First thing I thought was DRUGS! Where did my parents go?? They raised us great and everything. But now we are older they don't give a shit. My dad decided to take off on his family and never talk to them again, and my mom decided to turn to drugs. Great parents I have! So please comment and give me some solutions or answers PLEASE!!! Thanks for everyone who has been here for me over these years. They have not been easy at all!
