Need help affording weight loss medication and surgery

PLEASE please HELP Can I get an opinion, please? so I've been trying to lose weight over a year. docs have finally looked into it, and I was lacking a chemical that burns the fat. since I've been on this drug n carried on exactly what iv been doing the last year, I've lost 4lb. I've got to lose minimum on 1.5stone for my endo surgery. because it's so bad they don't want to leave surgery longer that 7months cause they think it's on my bowel too. but the NHS urgent waiting list is 2yrs 3months that's with 2Gps and a gyny specialist writing saying this is urgent so I've had no choice to go private and ar £500 a month I'm Really struggling. on another site, somebody said, "Why not ask a friend to do a go fund page ? You're doing it for surgery you desperately need. " what do you all think? Also, I don't have any friends that could do it for me, and I don't have a clue how to do it n think it's always better when a friend does it for somebody. Tbh even some to it would be a huge help but I've paid for first month whish I'm just hitting 3week mark (and ive lost 4lb so its clearly working and makes me feel better cause ube been doin this diet almost a year and weight didnt change by 1lb until i started thus medication) I need to do it for another 2months at least and I'm so worried how to afford it ..im disabled. im single from a nasty abusive husband.. ive had to pause the divorce as i need this surgery. I just about manage my bills. do you think this would justify a "just giving page . I just don't know what to do
