Throwing up and severe diarrhea

*Warning for details on diarrhea*

So I was officially diagnosed with stage 4 endometriosis about 8 years ago and my doctor cleaned up some scarring and unfused organs putting them back in place. He said I likely had Endo from the start of my very first period. Which makes sense because there were days I had to miss school (middle school mostly) because of throwing up and severe back and stomach cramps. I was near the toilet most of the day. but eventually it stopped being so severe.

I'm 33 years old now. I started my period today but for some reason last night I was up all night with straight water coming out one end and projectile vomiting. The stomach cramps are so bad.. I feel it in my back as well. I had to wake up my husband to watch over me because I felt like I was going to pass out while on the toilet. I'm still having these symptoms right now, I'm able to move some more without feeling like I'm going to fall over.

Has anyone else dealt with this? like I was really scared last night. It came on so fast and I didn't know what to do besides breathe through what was happening.
