It looks like everyone involved with aviation has had to deal with the stress of finding a way to do it, So No the butterflies are not unusual.
After doing a couple of lessons when I was a kid in 1973 then a couple in 1983 etc... I realised that short of getting the forces to pay for your training it is very difficult to get the time, the weather and the money all at once.
I got into the I.T. world then started my own business ( so now I have my own I.T. department) and passed my PPL last year after being taught by instructors who went the full commitment and get into debt route but still could not get a commercial job.
If you read this board you will probably get the feeling that there are more people looking for jobs than doing them. (O.K. all the employed pilots could be so busy happily flying they do not get time to logon here ).
I do not have a job as a pilot but I do now have 150+ hrs PPL, my own aircraft and time to fly it.
Plus I get to fly where I want when I want.
I am not saying you should not give up the I.T. job and go for it but just pointing out that there is an alternative that does also have some rewards.
