You need some hobbies and activities to release stress. Play crazy, have fun. Graduation thesis is actually very easy to write. Think about it, every graduate comes here like this. Hundreds of millions of people died from lack of credits, but few died from papers. As for work, there is nothing to be nervous about. I don't want to stay here, but I must stay here.
As for work, I personally suggest that you take part in voluntary love activities and go to poor mountainous areas. Any graduation thesis and work are just floating clouds. All they have to do is live and then live better. It's gone.
