Lodger agreement help

I have been living in a room with a live in landlord for 5 years. I originally had a one year agreement that then became rolling. The landlord put the rent up a year ago and I needed to claim more so had to sign another contract with a fixed term of two years so still have one year to go. It has an early termination notice of one month. I have been offered a new place which is near to my daughter and family/friends. At the moment I live 20 miles away from them and really struggle with my mental health so feel very isolated and am in poor physical health so find the travel very hard. I am so unhappy and want to change it. I need to be sure before I try to do this. I need to know if I can leave and not have to pay the rent for the year that is left? I tried to get help from my local cab but the person was awful and said they can’t help with tenancy queries. They said to call shelter but it says on their site you can only call the helpline if you’re homeless. My landlord used rocketlawyer to do my tenancy so I looked on there and they had two parts about early termination and they say opposing things. Will put them up. Please if anyone can give me advice, am at my wits end. Thankyou
