I want to complete a second apprenticeship

Hello!

I am 22 and I work currently as a Gardener in Germany (succesfully accomplished as my first apprenticeship) but I cant really do this phisically hard work because I got problems with my health.. so i need to learn another NON phisycal apprenticeship but to do that i must pay the college fees( a couple hunred dollars/euros a month....) . So.. I just want to work in a job what does not comes with that much or less pain every day.

Thank you all :)
