Mate , save yourself the cash , there is very little work out there for fi's we see 5-6 a week cvs' coming through the door .
The course , well the one I did was demanding and took a lot of work specifically GS , if your heart isnt in it then you will hate it , and as was said above think of your students , if you dont wanna be there you wont last .
get a decent job keep current fly as often as you can and keep your chin up , one day who knows this may all change
