Hi Chloe, welcome to the forum, everyone here has a loved one with addiction.
I’m sorry to read that your mum’s alcohol addiction is causing you mental health issues.
It’s a very stressful situation when living with someone with addiction. Is there someone close you can tell ? If not, the Adfam homepage offer advice and support/counselling. So do Drugfam.
From experience, ( my son has alcohol and cocaine addictions), I can say that , until your mum is ready to admit she needs help , it’s a tricky situation to try and get her to stop.
Please seek help and support for yourself Chloe, you need to look after yourself. Try Adfam or Drugfam, perhaps even speaking to your doctor put them in the picture about your situation.
Keep in touch here, people here are very supportive ❤️
