We all love our friends, or at least I hope you do. We would do anything for them and we'll love them for as long as we can, but sometimes your friends are going to get on your nerves. There will be times when you don't want to hang out with them, whether they're your best friends or just-barely-your-friends. I'm here to tell you that it is normal and that I, too, get annoyed with my friends. I, too, avoid hanging out with them for that exact reason.
Your friends are people, too. They have emotions, you have emotions, and sometimes they will just not line up. We all handle different things in different ways and sometimes we're not going to like the way the other person is handling things. Here's a not-so-fun story: I once had a friend, let's call her Jane. Jane loved boys. She was at the peak of her boy crazy years and anyone who knows me knows that I am the opposite of boy crazy. As the dutiful friend, I listened when she liked a boy, when she made out with a boy, and when that boy became her boyfriend. I did not like this boy. He was mean, condescending, and pushy. Jane was someone different when she was with him. Needless to say, I was very annoyed with her when she would come to me crying about this stupid boyfriend of hers, so much so that I would avoid hanging out with her. I still loved her, but if she was not going to take my advice and break up with him, then I didn't want to hear her complain about him. They broke up eventually and things were back to normal, but the point is that there are very few people that would not be annoyed in that situation. Anyone who wouldn't be annoyed is a saint.
We're all going to be annoyed with our stupid friends. No matter how stupid they are, so are we. We are stupid together and that's great. If you want my advice, give yourself some space. I am an introvert, however, so that may not be the best for everyone. If it's not, then I don't know how to help you except by saying that it's not weird. Being annoyed with each other means you care. Aw.
