@BreatheFocusRelax Sorry you have this too, it is completely shit. The every day pain, are you taking any pain killers for that?
I used to have that every day pain but a drastic lifestyle change saw me with very reduced pain, basically I stopped working and became a sahm. Now I am not suggesting you do this but it made a massive difference to my mental health, on very bad days I didn't have to push through and go to work etc and juggle childcare. Instead I could just relax, listen to my body and give it what it needed. And no I didn't have any family help as I lived too far away. Dh was absolutely amazing and my children probably watched a lot more tv than they should but they turned out great. 
For period pain I use a plug in heat pad, a TENs machine and a hot tub obviously not all at the same time. The hot tub is amazing because it allows you to get into different positions unlike a bath. As it feels like labour pain when I am on my period this is like a birthing pool that stays lovely and hot. Also a massage gun that pummels, which Dh uses on my lower back. It feels like how the TENs machine works in disrupting the signals.
I also did a pain management thing 20 years ago so sort of like hypno birthing I suppose. You acknowledge the pain, you know what it is, our bodies tell us something is wrong when we are in pain but labour pain we understand why we feel it. I do the same with the endo pain, I sort of accept it. I hope I am explaining this properly. With mine now though I know there is an end to the intensity because I know my cycle well, well I did until I started peri-menopause. I am almost 50.
Prescription pain meds when I do take them make me feel absolutely sick and when the pain relief wears off I am still affected by the codeine so I rarely take it. I have an incredible Dh and very supportive teenage boys who are great at looking after me if I need anything.
It took me around 10 years to get diagnosed and another year plus to get a laparoscopy. I took Duphaston and then Synarel for 6 months to shut my cycle down, then a laser laparoscopy with dye to flush my Fallopian tubes. Then I had 2 babies (told now or never.) I became a sahm when Ds1 was a toddler and before Ds2 was born.
I have tried every herbal remedy out there, none seem to work for me. I constantly look out for new information to ease pain etc, we can live in hope.
