I need my shopping theropy

I'm not a happy indivisual.
My dad recently learned how to text so I suggested that he could text me and talked about things we might not be able to talk in person. And now I feel regreted.
He started to text me nonsense and it gave me a difficult time. I don't know where he got all those negative thoughts but it really bothers me a lot. He's sinking in his own little miserable world and refuse our aids. I cried when I first got his text, didn't know what to do. I even forwarded his text to mom and mom was angry about it. I guess he's just lonely, I'm sure he is. The idea of communicating in another way so that I won't lose my temper and confront him. Texting him is a good way to calm myself down as I need to think what to say. But now I don't know.
My brother says he's got too much free time, need to keep him busy with something else. My brother once brought him a DVD player so that he could watch movies sometimes but he said no. It's not like we didn't try, we've tried what we could do but he just closed himself up.
Yesterday I spent a whole morning getting ready for a meeting and spent a whole afternoon being in one, had one class after work and then back home. And now I have to deal with him. Sometimes I just want to slap him and wake him up, and tell him to get real. My friends have been telling me that parents are sometimes like kids, they need attention too. But he's way too much.

Sigh.
