I’m putting myself out there, but things aren’t flowing the way I hoped

I don’t mean to sound negative, but I can’t really talk about this with anyone, and I could really use some advice.

For years I struggled with severe social anxiety. I could barely leave the house and was always the quiet girl sitting in the back of the class. Things started to improve when I began attending a university far from home and started working, which pushed me to interact with people more.

I’ve been trying to make friends and start conversations with my classmates, and at first everything seemed fine. But I recently found out that three girls dislike me and have been speaking badly about me

Lately, I’ve started feeling like people don’t take me seriously, and I don’t know if it’s because of me. Maybe I come across as silly since I tend to speak and act with a lot of energy, or maybe it’s my body language. I honestly don’t know what I might be doing wrong.

My question:

Have you ever felt put off by someone just because of the way they talk or behave? I’m wondering if I might be making a mistake without realizing it.

maybe I’m a bit sensitive today because a professor kept yelling at me during a lab session when I didn’t understand something, and those three girls seemed happy about it.....
