This is the first time I post on this subreddit, I just need to vent a little and to find support, sorry if this is not the right place to do so.

I don't know what to do with myself right now. I'm 23F, and due to covid I've been living at my mom's house since last october and having zoom classes. I have a master's thesis to finish fo next month but I can't focus on anything anymore and it has been going on for a few months. I have an attention span of 15 minutes at best and I just can't get anything done so I'm falling behind. I've been seeing a therapist to deal with the stress and anxiety and talking to someone helps, but it doesn't change the fact that the deadline for my thesis is getting closer everyday and I really don't want to fail this year. It's been so hard, I don't want it to have been all for nothing. I really want to succeed, but everytime I try to get to work I just get this feeling of heaviness that sets in and I feel trapped and I feel oppressed and I can't concentrate on anything, I just want to leave it all behind and go away from my responsibilities. Just the thought of studying sometimes makes me want to throw up. I'm not lazy, I'm usually hard-working and organized but this year it's been terrible.

I don't know how to deal with this, I've tried going out for walks, seeing friends, etc... but this feeling of anxiety is always in my head, I can't stop thinking about all the work I have left to do and I'm worried I won't be able to finish my thesis and pass. I feel like I'm drowning constantly, and I want to cry all the time. What the hell is this?
