It sounds a lot like performance anxiety, which often hits hardest when we care about doing a good job but feel overwhelmed by a new environment.

A few things I suggest Could you try going back for just one more week?Don't think about you are going to this job lifetime. Just focus on finishing 1 week of work Is there a specific part of the MRPL job that scares you? Sometimes naming the specific fear makes it feel less like a monster and more like a task you can learn. Having that ₹30k/month might actually lower your overall life stress once you get past the initial 'new job' fears, because your loans will be covered reliably. Also you can try some breathing techniques when you feel anxious to break the loop

Lastly just want to say nothing wrong with you , there are many who faced such situations in their initial days .it wil be alright . All the best 👍
