Want to change Project in Capgemini

I need some information about the project change or Process and any information related to the same. I was directly selected by the client account in CG. ( Joined in June 2025) After joining i started working on the project. From past 4 months, I have been feeling very low, having self doubts, less guidance from the seniors and no progress on my work.

Everyday I think of resignation, but due to my past experience I got the opportunity. My record was very good in my previous company and I have 5 years of experience. But here in the current project, I feel like nothing. No good work and less guidance. Feeling guilty for myself.

Please let me know what I should do. I need some genuine suggestions / guidance.
