I'm so sorry to hear what you're going through. Ideally, I think you could use a reset button. At the moment, your job, home environment and parents are all having a bad effect on your esteem, but things can change. You, can change it!
For your job, try and look for some resolution. There should be support available to address bullying (which is illegal) at the firm, so look to see if they can sort this out. If this doesn't work, then look for another job - there are more vacancies than applicants in this current market, so there will opportunities for you!
For your home and parents, the first thing you should try to do is talk to your parents. Let them know how they're making you feel - it's not an easy conversation to have, but one that can potentially change the dynamics of a relationship. If that doesn't work though, it might be worth considering other accommodation options - rented accommodation, AirBnb, or purchasing your own place with a mortgage. Having negative people will always bring you down, and especially with mental illness, that can hold us backx
Much love <3
