It's gonna be okay.
Be conscious of your actions and thoughts. Eat well, think positive, enjoy the movement of your body. It's magic after all, mind over matter. If you have a dream don't let it die. And if you don't perhaps you are already living it, be content with what you have and where you are, which is wonderful. Aside from this, my god, love yourself. The hate, frustration, disappointment that you may feel is so unnecessary. You failed, made mistakes, embarrassed yourself and faced unfavourable circumstances - but that's just part of life, that's the human experience. It can hurt like hell, though at least it's something, right ? And look at you, you're still here, you have this moment- you are this moment - so embrace it. Go forth and go within.
