Help Dawid change his last name!

My name is Dawid and I am a transgender man. I'm originally from Poland, but I'm a Dutch citizen. This means I currently have a female last name, ending in -ska. This causes me immense distress and difficulties in situations where I have to provide my last name. There is a way for me to change it to the masculine version -ski, however it costs €835, which is quite a lot for a full time student like me. I would be extremely thankful for even the smallest donations, thanks in advance!
