Assalamu alaikum - I'm too scared to ask someone to move so I can pray at work, thinking of quitting

Assalamu alaikum. I need to get this off my chest. Today I was late for work and it's a bit embarrassing but when I heard my boss coming from behind the door I panicked and ran from another way to get to my desk. I even hurt my leg in the rush. I felt so ashamed of myself for behaving like that and wondered why I'm so afraid of people. Later, it was time for Dhuhr and Asr (I usually combine them because Dhuhr time was ending and Asr was starting). Since I'm in an office I can't step away for long, so I try to pray together. There's only one quiet spot where I can pray and a man was lying there resting and scrolling on his phone. Dhuhr had only about 8 minutes left and I didn't have the courage to ask him to move. I just stood there frozen, watching the time run out. When the Dhuhr time finished I felt so useless and pathetic. I was more scared of my boss seeing me late, but for the sake of Allah I became numb and couldn't even speak up. I should have told the man politely that I needed the space to pray, but this is India and we don't always feel safe practising openly. I'm really sad that I'm like this. I feel like a sinner - Astaghfirullah - and no matter how many istighfars I say, it never seems enough. Sometimes I think about quitting my job because I don't know how to handle this. May Allah give me courage and make things easy. If anyone has advice or has gone through something similar, please dua for me or share what helped you.
