Sorry your suffering and I too have days when it gets the better of me - pain and exhaustion.
Having seen a number of gynaes I've finally been referred to endo clinic which is BSGE accredited and the gynae still didn't seem to take me seriously but the specialist nurse was lovely and supportive and helpful. She suggested more painkillers and different HRT (I've had hysterectomy and ovaries removed already) and when I saw GP she didn't want to prescribe as she is one of the "just get on with it, the pain can't be that bad!" That was final straw and I broke down so she did then prescribe tramadol and gabopentin as endo nurse had suggested and they do seem to control pain to a level that I can cope. I'm back to see nurse in a couple of weeks so hoping for next steps in treatment and hopefully another lap as it seems the only way to treat endo properly.
Try your GP as likely to be quicker to get appointment and just be firm that you need help as you just can't live your life. Hopefully they'll help. And give you good pain relief and a referral to a gynae.
