Who Is God?

Does this seem like a good question for a seminary student to be asking or does it seem like I should have that answer all worked out?  I've realized in the last few days, that good or bad...I don't know the answer.  I think it has to do with changes.  I've had one or two in the last few years.

First Mom and Dad moved to St Louis for a year, Mom had 4 surgeries (and yes, she was her usual pleasant and cooperative self...add in sardonic grin), Dad was diagnosed with Alzheimers (actually, they were both diagnosed with Alzheimers), Dad was on dialysis and oh - small things...Katie was a senior in high school and I was trying to run a company.

Then Mom and Dad moved back home (good for me, bad for them...Dad started wandering and falling, Mom was still Mom...) and the flights to Texas started.  I think I travelled to Bovina or Lubbock over 30 times in 3 years. 
Katie had started college (never did get to truly enjoy her senior year or grieve her leaving home), I moved my company to a new and improved location, sold my house in Ballwin and built one in Waterloo.  My best friend was diagnosed with Lou Gehrigs and my dog died.  Another good friend died of colon cancer and then Dad died.  And that doesn't begin to describe the trauma.

I was raised in Christian Science, but left them when they emotionally kicked me out for being gay, went through the New Age movement, found MCC or the "gay church", and then left all of that.  Found peace in gardening and being alone...and then found Diana's Grove.  I'm not sure I'm into Paganism as much as I connected with the kindness and spiritual hunger of those at DG.

I sold my company (and Praise God truly for that!) and have had almost 2 years off.  Now the last year has been spent exploring seminaries...but I am no closer to adopting a theology or creed.  In fact, I'm not sure God is anything but a human construct and Jesus nothing but a bunch of stories based on several people and mythology.  (my apologies to anyone I have totally offended)
Except that recently I was with a friend when she had a seizure and I prayed and "laid hands" on her.  Her seizure was mild according to another friend and I felt a "presence" when I prayed...a comfort.
