hey Thijs...
don't worry about it too much...
I've been in your situation, and most of us do
experience the same, whether after one year or after 300 jumps
a lot of people get a burn out and quit the sport at this point (seen it over the last 10 years)
I see it this way
you live for your parachute and get the FUN out of it,
OR you live for the dropzone (which you shouldn't,)
They will continue anyway whether you are there or not
Keep this in mind...
There are good friends and bad friends...
and maybe your good friends you think they are, might just be the ones who talk bahind your back and put you in this unfortunate situation...
I've been there, and every year I meet new friends and I loose friends just because that's the way it goes...
The only advise which remains :
Stay "low profile", don't hang around on forums too much but stick to your studying during the week, change to ANOTHER DISCIPLINE and be ready to do some more funjumps with people arriving this new season (don't forget that)
and most of all... know your friends
you know me...
good luck
