Work is suffocating

I was legitimately underqualified when they hired me for this job. So I went in with immense insecurity. The work environment is a small tight-knit science organization, so just imagine the atmosphere in that place. I’ve been staying late at work on top of working through my weekends to be on their level. They expect so much out of me so soon. My boss checks in with me literally every single day for updates, on top of our weekly staff meetings, and then they’re scheduling these grueling committee meetings throughout the week. It’s an absolute nightmare socially. I’m trying to learn, I’m trying to build, and they’ve figured out pretty quickly that I’m not that experienced. I get angry because they don’t do this to the other new employee. My boss NEVER talks to her. WHY ME BRO. I called the crisis hotline the night before I had to present in one of these nightmare meetings and they told me I was projecting my insecurity onto them and that they probably didn’t think negatively of me, and that I was an overachiever for staying late. Ok. Today I went in with a very positive attitude and was light and ready to work, but their negative attitudes brought me down after my last meeting with them today. So I really don’t think it’s my perception. Then the secretary was in a very bad mood and told me she didn’t want to come back to this place and that she felt taken for granted there. So maybe I do work with ***
