I don't think you should be or need to be worried about your stutter getting worse. I think for the vast majority of us, and I'm happy to be corrected (althought I hope I'm right) that it gets better or at least plateus for most of us. When it comes to tips you've seen online, here or heard it real life, don't get down if it doesn't work for you. I've tried a few I've read here, but none of them have worked. The only thing that worked for me was softening consonants. Unfortunately there are too many ways to stutter. I've seen a few videos of stutters and they don't all sound like me. I'm very glad that you have friends that ignore (I'd assume they're ignoring it) your stutter. It's probably the best thing to help it. The less you're made aware of it, the less anxiety you're likely to feel and the quicker it's going to get better. Don't worry too much about finding a partner. At some point you're likely to find someone who just doesn't give a shit. Edit: worrying about a new environment is a valid and sound concern. It was a change of environment that actually helped the most. If you're not being teased in high school for it, then I think it's safe to assume you'll be fine in tertiary education.
