Why doesn't anything work :/

So far this year I've had a mirena which was removed after 2 months because I was very anaemic and it caused constant bleeding which meant they couldn't get my iron levels up. I then had 5 shots of decapeptyl which failed to stop my periods and were abandoned because I had a massive pain flare after the 5th one and ended up in A&E. I was then given norethisterone, which was abandoned after 5 weeks because I had another bleed and massive pain flare. I've now been on cerazette for a month - I had a really heavy bleed and pain flare when I switched from the norethisterone to this which lasted for 10 days, and now I'm bleeding again and my pain is kicking in.

I am so fed up of these useless drugs that don't work. Sigh.
