Anger and Patience Connection

I have an issue with my patience and I have an issue with anger. I never really thought about there being a connection until I found verses about anger, and over half of them had to deal with patience as well. Anger hasn't really been a problem for me, except for recently. I don't know what is going on, but I get angry at almost everyone, and I definetely don't hold back. I lash out at everyone, even when they really don't do anything. I never thought that my patience would be the core of the issue. Let me explain. I will be talking to someone and they will be trying to tell me something, and that is when I lose my patience. That is when I start to go off on them and of course they will get upset. Another thing is I don't really know why I have been so impatient lately. I try and try to figure out why, but everything I think of is only really an excuse. I blame it on lack of sleep because of my work schedule and everything else going on. I also blame it on the stress of all this doctor stuff, but I have had these issues for a while now, not just this summer. Maybe I am getting impatient with it all now, I don't know. I'd rather not make excuses for myself, because thats not going to get me anywhere. I guess this is something that I just have to work on, with God of course. Yet another summer project!
