Stuck

[kılıç_mehmet]

I still haven't told any of my friends about my change in beliefs.

Have you converted to another religion? If not, I think it's best not to talk to others about this, but if you really want to *inform* them about this sudden turn of events in your life....

If you knew me in real life then you would gather that I'm most likely a theist because of the activities that I partake in during the week (church, youth group, guitarist for the worship team, guitarist for my own Christian-based band and bible study group).

If you don't enjoy these activities, you're free to quit them my friend.

The only place where I feel comfortable 'acting' like my true self is here, online.

Act as you are, or be as you act.

The problem I have started encountering with this is that because I haven't physically said a word out loud in real life that actually matches up with how I truly feel, it's like my identity has been split into two. I'm a non-theist in my head but a theist through my actions.

Well, there are times in which people feel like that. I sometimes feel like that when I have to do certain things. But I do them regardless for the sole advancement of my own agenda.
Religious things might be a different thing though, they are a matter of conscience.

Lately this has been having a really negative impact on my university studies. To make up for the lack of interaction with others as an outright non-theist I have been feeding myself with more and more information about what I think is the true nature of 'human existence' or basically secular information on religion (from a historical p.o.v.). This is the monologue that I am living where my true identity resides but it's taking away from what I should be focusing on which is my university studies instead of studying something not related to my degree at all.

That is an entirely different thing. I also take part in extracurricular activities, however, my first and foremost goal is to finish school. I must pay attention towards my studies before everything else, however it's really the boredom that catches me offguard before everything else.

The solution is to approach a friend and honestly tell them what I'm going through. The problem is that my circle of friends - which consists of theists and non-theists alike - is connected in such a way that it doesn't matter who I tell, the truth has the potential to reach key people that will turn my life into hell.

Key people? Hell? Where do you live, friend? The Vatican?

So I guess the advice I need is how to be able to talk about my situation honestly with someone but not give away everything. Do you think this is even possible?

I don't know why you feel the need to talk about a personal turn of events with someone else. How is this going to make you feel better? Do you want someone to testify to your old beliefs, or new ones?
Who are they going to complain about this anyways, to turn your life into hell?
