Trending @Cognizant; I got into a project. But now I am not able to stabilize myself. I am stressed and anxious as it will not help me grow.What should I do ?

3 weeks ago I got into a project and it's not according to career growth. I feel too stressed and also getting anxiety attacks. I don't know what to do ..how to tackle this. I don't know whether and how to get released from the project. Because I myself agreed to get into the project. By now after seeing the work and timings it is feeling too hectic and the work is also not of learning new skills. How should I solve this. What can be done and can I get released if I ask for it. As my client id and vdi access all have been created. Please help me out in this. I agreed to work I thought it would be fine. But now I am feeling I am stuck and don't want my career graph to go that way. I am a very beginner in my career. Completed 20 months in company. Help me out.
