stressful

I'm starting to freak out... I'm sooo stressed! Nothing beyond january is known at this point. I have no idea what I'll be doing, where I'll be living, who I'll be married to...... oh wait, that one I do know, it's more WHEN. agghh!!!
Do I go back to school next semester or take the semester off? If I take it off, where will I work? Will I even be able to find a job? I'll be kicked off my parents insurance so how will I be insured? Can I afford that?
When is a good time for us to get married? Will my parents be okay with that? Will all my friends/family be able to come? Will it be a good time for us both to plan? Will we get a honeymoon with that date? Should we do it when we want or wait until the responsible time? How do I balance keeping my emotions in check while still remaining excited? Are all of these thoughts even healthy before I'm engaged? But I need to know in a mere 2 months!! I HAVE to think them now! Will I be lonely in a new town? Will I hate the school? Will I hate being so far away from my family? What if something happens and I can't get home as fast as I'd like? What if no one comes to see me because the town is so far?

If you know me at all, you know that planning is a huge part of my personality. I can't do with all these unknowns! I'm going crazy and I can't just put them aside because their all important and all must be decided soon! I can't talk to my parents about it without being engaged (I just can't) and I can't pressure him to make that happen.
I know the answer is trust and God, so why can't I put that into practice?
