What if I'm a hard person to be around?
That would not be good. Why are you hard to be around?
I blame other people for everything and often do things that cause me to go into pain.
If you are aware that you are difficult to be around, you should try and change your behavior. People will like you more if you are pleasant.
I don't want to make it easy for them to spend time with me.
Why wouldn't you want to make it easy for people to want to be around you. It will be nicer for you to have people to care about you and the best way to do it, is to improve yourself so that they want to hang out with you.
