Usually in these matters when a person is asking 'Should I?' they are looking for someone else to decide
for them.
In all honesty, I can't say what you should do in this case. I'm not you, never visited Turkey let alone live there. I have no idea of the political and social climate in your region and I have no idea what makes you tick and the full reasons why you choose to be in the closet and why you feel compelled to come out now.
I can tell you this. You are not alone in your feelings. Nearly all LGBT reach a point in their life's journey when they feel they need to come out and be who they are. Some of us do it when we are very young, some of us wait until we are near our death bed - the rest do it sometime between these two points.
Everything you are feeling about being gay(ish) - is normal. We all have had these experiences these feelings. We all worried, we all agonized, we all pondered if it was worth the risk and we all wanted someone else to tell us what we should do.
Again, I do not know the full situation you are in. If you ave conservative parents (those opposed to the whole notion of LGBT) or live in a community or society where its a definite no-no to be gay, then do not come out until you are older, and able to fend for yourself - have a roof, a job, whatever not depending on the good graces of people who might up and kick you out for being yourself.
If you are reasonably certain that the folks or who ever you feel like telling isn't going to jump up, point and scream 'Three Headed Monster!!!!' and run screaming for the hills, then maybe its time to tell them.
How do you know if others are ready or able to handle the news? You can't really tell. I have heard of ultra-conservative parents who were anti-gay, vehnantly opposed to the idea suddenly turning a new leaf when their kids came out.
I personally had what I thought was liberal minded father, after all he kept a few token gays around to demonstrate he wasn't a bigot. Imagine my surprise when he couldn't cope with my being gay (nor my brother being gay as well).
So there are no hard rules at play here. Sorry. People do strange things under different situations, more often than not they do the unexpected (and unexplained in my books).
If you are uncomfortable to the point where you can't decide for yourself, then don't push. Stay where you are and relax, don't force yourself to have to do something where you feel the risks are too great.
You are only 16. So there is really no rush come out, you have plenty of time. My Crystal ball tells me you have until age 98...
