I feel like an annoying child every time I open my mouth

I’m so convinced I annoy everyone and it doesn’t help when the only people I’ve had as friends aren’t very close with me. It hurts so much to want to talk to someone but they don’t want to talk to you. I wish I could talk about my interests. It may not seem like that big of a deal but it’s such an incredibly lonely and frustrating feeling when you have something that you’re so passionate about but no one cares to hear your thoughts. I often get so excited over something and my first thought is wanting to tell someone but then I think about their reaction and how they wouldn’t care because our interests aren’t mutual. I hate having to shut down my excitement because I can’t share it with anyone. It makes me feel so depressed and I start to lose interest in whatever I was excited over. I’m trying to move onto social media where I can interact with people that are into the things I like but I regret every comment I make. I’m so incredibly afraid of people finding me weird or childish. Even when I get positive reactions, I can’t stop convincing myself that it’s only them being nice but they’re actually uncomfortable with how I talk/act. It’s so bad that I want to distance myself completely and just cut off communication all together.
