Please help change my name

My name is John Michael Jackson this is because I used to be a fan of Michael Jackson and having aspergers I do tend to have special interests in certain things I made the unwise decision to change my name back in 2015  Given the new evidence that's come to light on the TV and media recently I no longer wish to carry this name with me and wanting to work in care it will cause me problems in my near future I have spoken to solicitors who advise me that reversing my change of name deed is not possible and I will have to pay £120 to change my name back this I can't afford I know it's a big ask but I can't live comfortably carrying this name anymore I would appreciate any help anyone could give me Thank you for your time
