Sounds normal. Flying is fun and all...the stress of learning, training, being evaluated, canx-ing for wxr/mx/etc in primary training sucks. I wish I knew a way around it...
...that said, don't spin your wheels at a place that doesn't have their ****** together. There are enough schools that manage to be reasonably efficient despite the above problems.
Some days I think med school would have been easier/cheaper...sigh
