How can i be free from my obsessions and anxiety ? i am a single turkish man working as a engineer in a foundry.

Obsessions and anxie: The best is to think positive but this may be difficult. So i would strongly suggest you see a psychologist or a psychiatrist. The former would be better.

Psychotherapy: It's not clear exactly what you mean by obsessions, but both anxiety and obsessive-compulsive disorder respond to psychotherapy. Depending on your specific symptom and their severity, medication may have a role (ideally, temporary) , but psychotherapy will likely help. It may not be widely-accepted in turkish culture, but psychotherapy should help. See a psychologist to start.
