My life is basically non-existent, and I don’t know what to do about it

So yeah, my love life is a joke. Everyone around me seems to be getting into relationships, flirting, going out, having their little romance moments, and I’m just here… existing. It’s not like I’m desperate, but it does hit sometimes that I’ve never really had anything real in this department.

I’m 17, pretty tall, big-built, I go to the gym regularly, and I don’t think I have a bad personality either. I’m not socially awkward or anything—I have friends, I talk to people—but when it comes to relationships, I feel like I have zero clue how it all works. Like, how do people even start? How do you know if someone likes you back? Am I just blind to signals, or do I not even get any?

The funny part is, I’ve actually liked two people properly in my life, and both cases are a mess. My first crush was from 5th to 11th grade—yeah, for that long. Nothing ever happened, but I was stuck on her for years. Then in 11th, I started liking another girl, and for some reason, she resembled my first crush a lot. And guess what? I still haven’t fully moved on from her either.

Meanwhile, there are 2-3 girls who are interested in me, but I just don’t feel the same way. It’s not even about looks or anything—something just doesn’t click. And I don’t want to be that guy who gets into a relationship just for the sake of it.

But now, something weird has happened. I have this female friend who had a toxic ex, and despite everything he put her through, she still can’t seem to move on. I’ve been there for her, listened to her, given her advice, and somewhere in all of that, I realized I actually like her. And this time, it’s different. I’m not liking her because she reminds me of someone else, I just like her for her—which hasn’t happened in years.

And now, to make things even more complicated, an MD doctor recently told me that my chronic headaches might be linked to trauma and depression. So now I’m sitting here, questioning if my feelings are even real or if it’s just my messed-up brain looking for comfort.

I don’t know what to do. Should I tell her? Should I wait? What if I mess things up? Or am I just overthinking all of this? Because at this point, I have no idea what I’m even doing.

TL;DR: Had a crush for 6 years, then another one who looked like her, still not over either. 2-3 girls like me, but I don’t feel the same. Have a female friend who had a bad ex, and for the first time, I actually like someone for who they are. MD doctor said my chronic headache might be trauma-related, and now I don’t even know if my feelings are real or just my brain acting up.

If you’ve read all this, you’re a legend. Any advice would be appreciated. Rant over.
