Note/Context: the internship is a specificity of my country, I work 50% of the year in a company and the rest at school, I have a little salary and some day off (but no school holiday). My contract ends at the end of my degree. My official status is Student.
I've been working since the beginning of my third year of College for a big company A who sent me at a customer B (inside their buildings). I am now in 4th year.
For more than the first year It was wonderful, I learned a lot and the atmosphere was really good at the workplace. Surely I sometimes faced some difficulties with my code but I always managed to get over them. At the end of my first year, I had meetings points about my overall work, how I was feeling with the internship etc... Everyone was happy.
Since nearly two months, I changed team and now using a new JS Framework from Google (my boss put me there so I can easily have contact with the front end developper to help me going along with my new solo project).
After some weeks I can now say that it is quite a disaster, I really don't like the atmosphere. There are 3 devs and one of them is making useless and inappropriate jokes about musical tastes, my work speed, or my code quality which he does not have a clue of what I'm doing since he is a back end dev. He is just hearing when the front dev "helps me". He is known to have this behaviour but people seems to have dropped the case. One point for him, he seems to be a very good back end developer.
The second and main issue is that as I said I was put here to get help if I needed to since my school does not provide any course on this Framework and I do not have a lot of experience in JS, but I do NOT receive any assistance. When I'm asking a question, they make fun of me and I feel the front dev is not that pleased to help me. So I ask him for help only when I'm stuck for days.
I'm doing overtime to compensate the fact that I'm quite slow and buying books over the new Framework (+ I always have the documentation near me).
This situation is putting me under a lot of pressure and I fear that it will impact my health. It has now began to wear my motivation and I start to feel useless.
What should I do? Am I the trouble Here? Can I ask my company to send me to another client? Do I need to question my initial choice of studies?
