I'm planning to do a full-time MBA, but I'm scared. Can someone guide me?

I'm currently working full-time at Deloitte and seriously considering doing a full-time MBA. I want to grow in my career and feel an MBA can open better opportunities for me, both in terms of learning and future roles. But honestly, I’m scared. I’m worried about whether I’ll be able to handle the pressure — the fast-paced MBA coursework, group projects, presentations, and everything that comes with it. I also fear whether I’ll be able to cope with the post-MBA expectations in the corporate world, especially in managerial or leadership roles. I sometimes doubt if I’m cut out for all this or if I’ll just end up struggling. Has anyone else felt like this before starting an MBA? How did you overcome the fear? And how different is life really after an MBA? Would love to hear your thoughts and experiences.
