cruise?

My oldest sister is taking me and my hubby on a cruise in march.  we all have to buy our own tickets ans stuff but she promises to be there and watch over us(me) and make such we (I) don't get into trouble.  I'm a little afraid because of how I feel right now.  I am very tense and depressed.  THis cloud hanging over my head seems like it will never leave.  I would cry if I had someone to hold me.
