I really hate the person I am and the life that I live.
Is it possible for me to become a completely different person or would I at most just be living a lie?
Thats very edgy
I suggest you think about this and spend some time growing out of it so you come with your own conclusion.
Specially the first sentence.

Please explain how this is edgy you retard.
>>17820512
If you are OP I don't think you should be calling anybody retarded...
>>17820516
Don't understand what is so controversial about not being happy with my life and the sort of person I am. I'm pretty sure most people feel like this at some point in their life

Never said any of that was controversial.

Don't know if you're the same poster but what did you mean by edgy then?
You can't change your core, but very few people would gain anything by going THAT far. You probably don't need to either. The rest can be done, but a warning: this is an extremely unpleasant and error-prone process, and screwing it up is bad.
The first step, before you do anything else, is to start seeing a therapist, or at least a counselor. Like I said before, this is error-prone. You will need feedback. A therapist provide that. Not a psychiatrist: this isn't the sort of thing they specialize in (though if you need to see one for other reasons, you should of course do that).
The next step is to plan this out. Who are you now? What do you want to become? To help wih the former, look into doing what Alcoholics Anonymous calls a "fearless moral inventory". To help with the latter, I recommend Christopher Peterson and Martin Seligman's book "Character Strengths and Virtues". You need a grasp of where you are now and where you are going, or you'll get distracted and/or lost.
Next is getting some structure and discipline into some aspect of your life. Joining the military is an extreme solution, but I do not recommend it (in your current state you risk washing out anyway). Martial arts classes are common for this, provided you can find a master who will actually work you hard. You don't need order and discipline to take over your life; you just need practice working with it.
Note that all of this is prep work. We haven't even started the breakdown/rebuild yet. The first piece of that process (but also the last bit of prep work) is a change in philosophy. You are no longer "what you are"; you are now "what you do". MAKE SURE YOU HAVE THE THERAPIST BEFORE DOING THIS, as this step is often quite painful. People going through it have to face what they're doing, and that often doesn't feel good.
But once that's done, you will have two new and powerful tools: the phrases "this is what I do" and "I don't do that". You will know what to do with these, when the time comes.
