Frustration

Lately there seems to be a lot going on. A few months ago I felt really convicted about some of the conversations I was taking part in. I decided that I didn't need to talk like that. Gossip is harmful and I really should have always known better. It affected my life a lot growing up, and still affects things today. Now things are at another level. In distancing myself from all of that has now made me the target. The thing is that I KNOW what's going on and I feel like I can't say anything. I've always believed that I'm on my own. I need to take care of myself, I need to defend myself, and I need to keep people at a distance. It's me on this island and everyone else is across the ocean. I'm so big on keeping my opinions to myself and my life to myself. I believe if I share something with one person, it doesn't mean it's free game for everyone else to know about or to discuss. Now I'm having the issue that I just don't know how to respond. I'm so frustrated, and quite honestly extremely angry. I don't want this anger to take over, but I feel like it's starting to. How do you stop it?? I know that the Lord is trying to teach me to trust Him, and let him fight my battles for me but it's so hard!!! Trust is hard for me, I have a hard time with it. I struggle with letting people in and I'm afraid that all of this is going to make me let less people in. I need some serious prayer. I don't want bitterness to take over. Lord help me!
