Hi everyone Thank you for all of the advice
since I first posted I have tried to just have a look at what I eat and drink to see where I am and why I keep making unhealthy choices and I still can't particularly figure it out.
When I go on the bike I actually do really enjoy it, I listen to my music and feel great afterwards! I think I just need to make it become more of a habit, I live with my boyfriend and he would rather I cooked him dinner and watch telly with him when I get home from work rather than dedicate any time to myself ( that's aanother story your another day!) Anyway Thank you for all the advice, I need to have another read through
