Unlike the other comments so far, which are all assuring you that there's plenty of friends out there and so on, I'm going to take a different approach, focusing on this:

I hate myself so, SO much. ... People always say "you are not alone"... But I AM.

I'd say this is probably the root of the problem. It is not merely that you have no-one to call a friend, but that time spent with yourself (which is exclusively how you spend all your free time) is time spent with someone you hate.

In a way, this dilemma is the very essence of the depressive condition. You hate yourself because you have no friends because you hate yourself because you have no friends, and on and on.

Let me tell you a short story, maybe you can relate so that my advice doesn't seem unrealistic. My own struggle with depression started with an emotional trauma that kicked off the familiar reinforcing loop: I felt awful for a good reason at first, but quickly the good reason dissipated while the awful remained, and I began manufacturing reasons to justify the arbitrary feeling. I must have felt bad because I was bad. And, let me tell you, that kind of attitude doesn't do wonders for your social appeal. I quickly found myself without friends, plus a profound inability to seek help from my family - you see, they kicked off my crisis of confidence in the first place. Therapy provided no actionable material - it was just me explaining how I couldn't account for my arbitrary negative thoughts to a therapist who seemed as confused as I was.

Day after day I'd see wonderful recovery stories from depressed people about how they had a friend or family member who wouldn't give up on them, and dragged them from place to place until they could manage on their own once again. All the advice said that a strong social support network was critical, but... well, you understand, I take it.

The point of the story is this. The cycle isn't necessarily broken by acquiring those things you have decided are the reasons you must feel the way you do. It can be, true. But it can also be broken by giving up those justifications as important. You could satisfy yourself by making friends, but perhaps just as easily - and more assuredly - by giving up your need for friends.

As said Seneca in Letters from a Stoic well over a thousand years ago: “True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. A wise man is content with his lot, whatever it may be, without wishing for what he has not.”

I hope that perspective may prove at least as helpful as all the advice on acquiring the friends you seek.
