So recently I started working for a multinational company as a student. I'm in home office 80% of the time. Most of the members in my team are indian, they have been nothing but nice with me so far but last week they added me to a weekly call where I'm the one who leads the meeting. Everytime I get asked a question with their usual accent that I thought I was used to, I don't understand anything from it. I repeatedly apologize, make up excuses like my laptop doesn't work or my internet is bad just because I'm so embarrassed that I don't understand what they're saying. I feel like an idiot for asking for everything in e-mail (which they don't reply to at all). And of course even after a short call I'm shivering from anxiety. 

I think I speak fairly okay English. Repeatedly feeling like a dumbass doesn't help me getting over my anxieties though.
