I am currently serving a mission in mexico but if I go home my parents will cut financial support

I have been serving a mission in central mexico for over 14 months. I stopped believing in the church when I was about 14 when I got some friends who were athiests. I never got any magical answers or revelation from reading the book of mormon. In fact upon invitations from seminary teachers reading the book of mormon only made me realize that is it mostly plagarized from the bible and other sources.

So living in a neighborhood where about 1/100 people are not mormon has kept me putting on a show for the last 6 years of my life while I have had other mormon friends who left the church during and after high school I kept going because if I don't continue I am sure my parents will cut all financial support and I don't know how I could finish school without financial support. So I went on a mission thinking it would be a good diversion from normal life for 2 years. It has been good for me in the sense that I have lost 60 pounds and learned another language but I just can't live with myself spouting lies to all these people.

I have dicked around with lazy companions for 7 of these 14 months. Going to cyber cafes here in mexico every day to browse the internet or just wasting time watching movies and playing games in the houses of other people. I still don't want to be here. There is nothing more I can gain from being here. I am not losing weight and I already speak fluently. I have been studying for school by reading text books on the iphone 3g I bought with my most recent dead companion but I won't be able to do that if by chance they put me with a brainwashed TBM

So what do I do? Should I just keep up the show for another 4 years until I finish up the university or do I just go home and hope for the best?

FOLLOW UP

Sorry for the vague missionary slang. Dead companion as is a spiritually dead companion. They just call people in this mission Muerto (dead) Frito (Fried) and Phariseo (Pharisy) to refer to a level obediance.

So I have 2 weeks left in the change with this current companion. I will try to find a job in computer repair or network/server administration (have 4 years experience from job with high school managing their servers) when I get home and start school in the spring. I will probably ask to get sent home once this change ends unless I get sent with another lazy companion to make another few months of vacation out of this before ending the mission. If they cut me off I will go for FAFSA and if really necessary some student loans. I could attend SLCC in the fall for the generals that I still need and then go to the U of U when my 2 year leave of absence runs out.

Also I really want to try out skyrim.
