Have been since yesterday

I have to put in my two weeks notice today
Since I am about to start a new job here in a couple weeks

Problem is - I'm afraid of my store manager/head boss
I have been the whole time I've been working here...
Everyone else I get along great with and really enjoy
But this guy is just a major d-bag

And any other job I've had in the past
I've just left without warning.
So this whole two weeks notice thing is new to me.

PLUS I have a bunch of time requested off during those two weeks...
Some to go to MFM (yes, I'm going.)
And another weekend to go on vacation with my friends and family
So it's a MAJOR chunk of time I am requesting off...
So I feel guilty about that too.

I'm just freaking out so bad right now
But I want to do the right thing.
I'm panicking...
