Needing some advice!!!

[Bexallina]

Hi everyone. I've not long been told I've got endo, and I've just started taking medication for it...however the last few weeks I've been on cerazette and I just seem to have got worse. I'm completely exhausted, i bleed quite a bit, I've got no appetite and I'm starting to lose weight...I've got a million more symptoms but there's too many to list. My doctor wants me to take these tablets for 6 months. I work funny shifts at work and it's getting to the point now where I don't think I can possible do it anymore. I'm up on my feet all day, walking up and down a shop floor. I feel really stressed every time I wake up that I have to get up out of bed and go into work. It's such a struggle. I am planning on talking to my manager today, but I think she's just going to think im a drama queen and making it up. I just wondered if anyone has been in a similar situation and had any tips on how to approach the situation. I feel like it's the best thing to do because I don't want to let them down. If this carries on I'll be phoning in sick everyday! I can't physically do it anymore!!
