Glandular Fever and weight loss??

Hi Everyone!

Since June this year I have been suffering with all sorts of bad stuff, well finally its been confirmed as glandular fever with recurring ear infections and constant throat infection ( having tonsils removed in a few weeks). I was just looking to find someone who has been through this and still managed to lose weight, at this stage I am so weak with so little energy that I am eating whatever I feel I should eat and staying at roughly the same weight with 0.2kg variations. I should be loosing weight for surgery but dont know how to do this . Does anyone have any experience with this at all please?

Thank you
