As the title reads I need advice on how to deal with my manager at work (I work in a garden centre in the UK). Since I have started I have been treated as incompetent and have had the very thing I have a college education in constantly explained and repeated in a belittling way because my manager assumes that because I don't know the specific plants we have at the moment and where they can be used so instead of getting trained in that she assumes I don't even know how to maintain the most common and widely available plants that I work with everyday and she re-explains it every day. However recently I have a horrible day because of her accusing me of not doing my work to which I then had to redo everything after my lunch break and then being accused of taking a 50 minute lunch break when in reality after my break I had to use the bathroom and then I redid the job I was accused on not doing in the morning. Because of my personal trauma and mental illnesses it caused me to have a panic attack and cry during work and couldn't even defend myself. Now I have joined a union but I feel gaslighted and feel like I can't remember the situation correctly, even now as I'm writing this I can't sleep, feel extremely depressed, anxious and scared even thinking about going into work tomorrow. This isn't the first time this has happened but it has started me recording every incident in writing especially. Every day after working with her I care less and less about my performance, I'm loosing the passion that made me take horticulture in college and what made me take this job and get closer and closer to quoting every day. After the incident I talked to a coworker and learned that I wouldn't be the first person to quit because of her. I want to quit but I'm desperate for money after not being able to find work in almost a year. I'm desperate for advice, I can't sleep and I'm shaking just writing this. I want to confront her in the morning but I'm not sure if its the best idea or if I'll even have the guts to do it.
