I know you're scared, and life seems out of reach. But you are living your life right now. Stop worrying so much about proving everyone right, and stop trying to be so good. Be a little bad for once. Drink a little, and spend a little on things other than materials. Furthermore, you have a style. Stop worrying about your sexuality, and start expressing yourself. Your sexuality will be over soon. Trust me.
Stop worrying about the fact that you are a big baby. To be honest, you're only 17 living in a country on your own! It's ok to be a baby still.
Also, stop dressing like a boy, just to hide your body, stop dressing bad just to spend less money. Spend money dude!
Also, stop gathering waste material. Simplicity is the answer.
And don't punish your self. You are good at what you do. Just do it! Learn to love your self a bit sooner, to save me some trouble. STOP TRYING TO IMPRESS PEOPLE. You are pretty amazing already, and the ones that should are already impressed by you. Instead try running after people that impress you, and learn a thing or two. Make more Erasmus friends. They have a lot to teach you. And I love you for all your experiments. But at the end of the semester is where the experiments need to end, and you need to just do the basics. That's all you need.
And I know that you don't know how to place all the pieces together, just give it some time, everything will put itself together when the time comes. Stop hating your self over these things.
Even if you ignore all of it, seriously. I just need you to be kinder to your self and love your self and love your body. You are a good human. And you have a nice body. And the love in your heart is radiant right now. Don't let go of that. Don't be angry, stop punishing your self. You will have a hard time getting back. Please just be happy.
Love Always
Anna-Maria
