Have you ever felt uncomfortable in a friendship?

I have this friend who I treat as a best friend. We were there for each for both sad and happy moments. We saw each other cry and laugh, fail and climb up again. We also have this agreement to open up if we find anything annoying about each other. It used to be a good rule. But lately, it's like she's oversensitive and sees the bad even in the smallest things I do.

It made me ask her if she truly knows me because she tends to misinterpret everything I say and do for the worst. For example, I kept reminding her to watch Avengers Infinity Wars before we watch the End Game because I know she wouldn't understand a thing if she doesn't. Next thing I know, she thinks I'm acting all high and mighty and looking down on her.

I care about her. I truly do. But just the thought of having to adjust to her every whim for her comfort makes me feel like having a personality replacement, one that I would hate because I couldn't be myself around her anymore.

Suddenly, I can't help but think that maybe she doesn't know me as I thought she does. Suddenly, it's too much and it feels suffocating to be her friend. I need air.
