Hello! ;) 
I have been using this page website for one month, but I can't have not learned a lot because I had a lot of exams in during this that time. 
I like music, and I love Christina Aguilera. I wanna be journalist (an investigative reporter) and I'm studying for this that. 
I'm searching for someone who I can speak with every day and progress to improve my English.

"wanna" is typically used in spoken English and is very informal, but I don't think most people actually write it despite how often they use it when speaking.

"with whom I can speak" is correct and better than "who I can speak with" but feels very formal and a little bit stuffy. 

Good job! :-)
