There are two things going on. The primary events weren’t just the sight blood — it is the sight of your blood as the result of a self-inflicted wound. This is important as the episode with the camel followed the self-inflictions.
The university in your hometown is one of the finest in the Netherlands, with a renowned medical facility. Use this nearby resource. I highly recommend you talk with your mom and dad about going there for an evaluation because you are hurting yourself in the process. There are various terms for being fascinated by the sight of blood, but these seem to be less related to your experience. The main thing is your self-harm.
The fact that this bothers you and you do not want to hurt others is important. I am very glad you wrote us here at Psych Central and encourage you to be brave and take the next step of asking your parents for help in getting an evaluation. They may not understand the reasons why you do this, but they will want to help.
