I am so sorry. Hope that at least biopsy results are fine. And yeah it sucks...the burdens of having bloody ans (especially with endometriosis) bloody periods, hormonal changes that go with it, birth pains, taking precautions if you don't want to get pregnant...
On the other hand there are positives also. Feel good hormonal cocktail when you're pregnant and few weeks after birth while bonding with a child, the miracle of being able to grow and give birth to human being, not being forced to go to war or doing the most tedious jobs in society...
Life is a one trade of after the other and being a woman sucks whole lot less than 100 years ago.
I hope that pain will stop soon and wish you luck on your part-time job.
P.S. If you're not worried about addiction maybe you can buy some kratom based products for few days to help with pain
