I think I've mentioned something about my history of stomach problems on one of your previous posts, but I'll pretty much sum it up here again because I truly do understand exactly what you're going though.
I lost almost 25 pounds, I was the skinniest I've ever been in my life - I was so weak due to the fact that I was so skinny and everyone (including a handful of doctors was extremely worried). I was nauseous 24/7 and could barely stomach half a meal a day, intact there were many days I would go without consuming food at all. Sometimes even the thought/smell/sight of food made me want to throw up. I was experiencing horrible abdominal pains that would come and go whenever they felt. I started having a lot of bowel issues and there would be weeks where I was completely constipated and then weeks where I pretty much had diarrhoea (I'm sorry for the too much information). My stool always looked weird and abnormal and was constantly changing colour, texture and size.
I also would cry constantly Bri and was convinced I had horrible parasites in my stomach that were going to take over my entire body. I was convinced that I had picked up a parasite while I had been on vacation a few months back (even though the vacation was in December and my symptoms started around March). I thought of every worse case possible scenario. I had so many stool samples done because I read that if you have parasites then sometimes they don't always show in your stool and it make take a couple tests (so I had like four) and different kinds too. I was so convinced something so sinisterly wrong with me, I was a total mess.
My doctor ended up being pretty concerned too because I just kept losing weight, getting sicker everyday and the stomach problems persisted. I got scheduled a colonoscopy/endoscopy with checks EVERYTHING down there and takes biopsy samples to make sure nothing is living in your stomach or intestines etc. On top of that, I had multiple abdominal, colon etc ultrasounds completed to make sure again that nothing was missed. It took a couple months to get the results back but it turns out that I had nothing more than a touch of IBS and overall just a pretty irritable stomach that can be aggravated quite easily. I started seeing a Nathropathic doctor who got me on some really good nutrient shakes that helped me to build back my strength and bodies nutrients (because at that point I literally couldn't stomach any food - I literally just drank these shakes and water). I drank the shakes multiple times a day for a bout three weeks and slowly worked my way back into real food. I still have some stomach issues but nothing as severe as I once did. I've had a lot of help in getting better and I'm still not there it. It's a huge process but step by step you can overcome it I promise.
Pretty much between my mom, my doctor and myself we figured out that this is how we think my cycle started:
University (First year, very stressful, bad eating habits to begin with) - Started to eat less and less all the time - 2nd Semester of University (My HA kicked into full force - I was having panic attacks on a daily basis) - the constant anxiety and stress just wrecked havoc on my stomach with started the nausea and not wanting to eat. Because I never felt hungry or I felt too sick to eat, I simply just didn't eat - which resulted in my body starting to lose an incredible amount of weight - as your body is losing weight and not gaining absolutely any good nutrients you're going to feel even worse and worse and it's just going to make you feel horrible (it's a horrible cycle).
I sympathize so deeply with what you're going through Bri, because when I experienced this it was truly one of the worst/hardests times on my entire life - I ended up at the ER/at the doctors atleast fifty times. I know it's so hard but it can be reversed and I know you can do it. I'm always around if you need to talk about anything or just vent (you can always personal message me) and if you have any more specific questions feel free to ask - I understand exactly what you're going through and I'm so sorry.
I can promise you one thing though - You are going to be okay, as hard as it is to believe, you will totally one hundred perfect fine. Remember that you're strong.
