Kolja,
If you go for it now you should have all the necessary qualifications (if not experience) by the time the market picks up again and jobs once again become more plentiful, which they always do eventually.
I began my training in 1990 just before the Gulf War began and the World recession hit. However, by the time I had my frozen ATPL and a selection of performance qualifications for various aircraft types, the market began to improve. I was employed by 1992 and now enjoy being a captain on a state-of-the-art regional jet with a reputable company!
If you don't follow your dream you may forever regret it.
