Sorry you had to go through this, Jassica.
I would suggest you get out. You are still in the first year of PhD so you can start looking around and see which other lab you could jump to. Don't tell your supervisor until you are ready to make the jump. See which lab has good working culture and project that you are interested in. Start talking to other labs and their students to learn more about them but don't say anything about wanting to go until you are certain that that is the lab for you. Then talk to the new potential supervisor. Once you have confirmation of new supervisor, go through your Graduate school to change your supervisor. At that stage you can tell your current supervisor. All the best
