I am so Sad!

Today me and my family were supposed to go camping
for five days like every year. I was so excited this year in
particular, and now we're not gonna go
because some stuff going on at my dad's work.
I reallly sad,
and I don't want to get angry
but it would really help some kind of advice :(

I want to believe there's a reason why we are not going,
beacuse I believe everything must happen for a reason,
but its' too sad to look on the brightside,
I had been waiting for this trip for almost a year and now is just not gonna happen:(
