I am searching for an English or American pen pal friend English

Hey!
My name is Winona and I am from Germany. I‘m searching for an English or American pen pal friend, because I want to improve my English. Next year I have my English exam and for that I need somebody who can speak with me about everything. This would give me some safety. So I can make new social contacts and I could learn a better English with fun. I am looking forward to it. I hope some of you could help me with that.
