A few things:
1) You're making a lot of comments about "friends". I suspect the kind of friendships you're after aren't the casual "we share an interest" friends, but the more serious "we really care about each other" friends. First and foremost, no one has a lot of those friends. No one. They're hard to find, take a lot of work to keep, and you're lucky if you have a tiny handful of truly special friends in your life at any point.
You seem to be suffering through a depression/period of self loathing right now, which is making you extremely self-focused. This isn't going to help you form deep friendships. They don't happen overnight. No one spots you on the street and thinks "I want to befriend that person, about whom I know nothing". They form over time through the cumulative effort of both parties. You trust, and get trusted. You open up, and they open up in turn. The best way to GET a friend is to BE a friend. Listen. Show respect. Show concern. Take a genuine effort in their life and welfare and interests. Be there for them, unreservedly. Will everyone pay you back in kind? No, but bad/unhealthy friendships are part of growing up and they're something everyone must endure at some point. You do the things I specified, though, and no matter how loathsome you think you are, you'll come to have close friends who respect and rely on you.
2) See a doctor and talk about depression and anti-depression medication. You're assuming a nihilistic/hopeless tone and threatening suicide, so you need to do this post haste. Look into getting on an anti-depressant, and, once you're feeling a little better from it, you need to make sure you're eating right/sleeping well/exercising. You're going through a period of life in which huge changes in both your personality and circumstances are to be expected, and this can cause tremendous emotional upheaval. If you've never been through a clinical depression before, it can be a terrifying and draining experience. Please take the first step and get some help.
3) You need to consider finding a counselor or therapist to talk to about your gender dysmorphia issues. It's not as uncommon as you'd think, and feeling that way is not an ironclad guarantee you're transgendered, but on the off chance you are, it's something you want to discover about yourself sooner rather than later (for many reasons, not least of which how much easier transitioning is when you're younger). Depending on how strong/pervasive these feelings are, they could very well be contributing to your self-loathing and depression.
If you want to talk about any of these points in greater detail, or you want help/advice with anything, please don't hesitate to message me.
