Yes, you definitely need to stop scouring the internet for medical / dental horror stories. Extractions are sometimes necessary. I had to have two in advance of my braces, plus a bone graft. My ortho provided a strong rationale and I went with it.
I'm 64 so here's a little pep talk.
Look to the long term and the end result. Decide what you want -- a better smile, more confidence, and so forth. There are no guarantees and you'll need to find your own way. Most if not all of us were concerned to some extent what others would think about braces. You're smart to investigate braces at your young age. You'll have that many more years ahead of you with the smile you've always wanted. With me, when I was asked why I got braces I replied (deadpan) "Well, I wanted to have the nicest smile in the cemetery." (Apologies to the old-timers here who have had to read that little quip over and over.) Of course in response I got this look "Is he serious?" and awkward silence. I loved it, but then I have my own set of issues
Self confidence will carry the day with the ladies. Braces or not. And not that I am any expert, but I suspect that many women will secretly applaud your desire for self-improvement and willingness to be inconvenienced for a while. As an RN I've worked with women my entire career, and in general they are less superficial then men and look for the goodness and integrity, etc. This is a gross overgeneralization but trust me your self confidence will pique their interest. No, I don't know how it works, it just does. And the braces may give them a reason to start a conversation with you so start thinking about what you are going to say when they ask you "How do you like your braces?" And for the unspoken question, braces do not interfere with romance (kissing and so forth).
I've always been a bit surprised that many people don't notice, and the ones that do notice really could care less. Every once in a while I'll catch some doofus staring at my mouth and I can hear the wheels turning and creaking in their heads as they try to figure out why someone at my age would get braces. I turn and look them in the eye with my patented death stare. Did I mention I have issues?
You'll do fine. You aren't the first and won't be the last. A couple of years from now you'll be wondering why you waited so long.
Best of luck to you.
