dont like brother

Hi everyone i don't know who else to turn to but ill try and make it short. I graduated last year and have got a job about 10 months ago. this job is in a call center and very stressful I haven't always been the most confident guy due to being bullied at school and at home by my older brother. i suffer from depression nd anxiety i went to a doctor and tld him that this might be the root cause of why i feel anxious. My brother was a bully in our teens he has a temper and used to take things out on me such as hitting me, stealing my stuff and always insulting me calling me names, etc. This effects me so much that i put on weight in the gym just so i can be left alone. I have been in a depressed sell and told my mum about the situations in the past has affected he is okay now but still does dickish things sometimes. and what hes done over the years so she told me to confront him about it. so we sat down one night and i told him how it affected me before i even got to finish he was swearing at me trying to intimidate me etc such as clenching his fists and he was calling me pathetic that this has affected me he said i was pathetic that im on tablets and that I took time off work. we still live together and i don't know the best way to go around this any help would be appreciated thanks.
