Schoen guten abend,
I could recommend a few things to consider doing:
Enroll in an online/distance learning education. RDI for example gives you many different online courses to choose from. I, for example, have just enrolled in the BCs on applied psychology. You get a good span of up to 9 years to finish, and you have will get a bachalors degree. All study materials available online and almost all exams etc is done online, no class room etc.
Get into some serious sports work out. Get in a f@cking good shape. Running, cross country, hiking etc.. Start a hobby you always dreamt of. Something that you can always look forward to, as you leave home to go away for work/standby.
Good
Best of luck and happy flying..
K.
