I just feel like I needed to vent about something. I’m an international student and I’m already stressed about my exams that is in a few weeks. I’m also dealing with home sickness since I’ve never been away from my mom from this much. I live with my cousin and I really really do appreciate and respect her I really do. She’s over 20 years older than me and I am a very chill and good kid so I try to listen to her and do everything correctly. But the way she was raised and the way I was raised is not the same. Today I had rock climbing and it was supposed to finish at 7 pm but we finished 10 minutes early. She sent me a message about dinner on whatsapp and I replied to her as soon as I can but she got mad because I replied to her 20 mins late. I did explain to her and I apologized and told her I will reply fast in the future and then she told me it’s okay. but I feel like she doesn’t look from my perspective and think about what I have to do. Like im not gonna be able to check my phone every single time she messages and reply to her two seconds later. Even today I did reply to her as fast as I can I finished rock climbing at 6:50 and I replied to her at 6:52. It’s like she’s looking everything from her point of view and think I have nothing to do. I got really scared when she texted me cuz she told me " I won’t be patient like your parents" and stuff. I’m already dealing with a lot of stuff from school and being away from home and she thinks I’m like emotionless cuz I don’t display anything but Im actually a really really emotional kid. I really just want to be left alone or just go anywhere but my place. I get that she was raised with a strict dad but I feel like she should’ve been more understanding instead of just telling me stuff like that bluntly.
hello, I understand that it can be challenging to adapt to a new change in environment whilst grappling with exams, and I hope that exam prep has gone well on your end 
perhaps sharing your thoughts with her over a meal will help
