Latest blood test results are in. They are SHOCKING btw (might be that bad because I had been eating sub 1000 calories a day for a few days when the sample was taken).
For reference, here's what my hormones looked like last December before I'd ever touched finasteride:
What's strange is that in April, a week into my re-feed after a ten day water fast, my total testosterone levels were reasonable though I still had ridiculously high E2 and SHBG:

Thankfully, I've managed to start eating again a bit more. Sticking to white rice, eggs, chicken and spinach. Brain isn't melting down from eating like it was when I was hospitalised.
Brain swelling/pressure eased the last few days prior to today. I actually managed to play some online PUBG and Halo. This is quite significant for me so far (don't laugh!). Previously, it felt like my brain couldn't handle the information on the screen and I couldn't concentrate on it. I've been playing in the mornings mostly, before I eat my first meal of the day.
Today brain pressure has returned to a moderate degree. Got worse after eating, had to stop my mum talking to me, mid-sentence, as it felt as though my brain was about to explode again. It's subsided a bit now though.
Sleep has been pretty poor this week. Couple nights there where I was waking up every hour or two. Exhausting. Bit better last night.
Haven't fapped in 17 days, penis is practically numb while flaccid, haven't had any waking erections of note and nocturnal ones have been mostly 60%. Haven't tested with porn to see if full erection is possible, honestly, my neurological sides are that bad where I haven't got the energy to worry too much about my dick at the moment. Saying that, when washing in the shower currently, it feels like the structure within my penis is disintegrating? My shaft skin is bunching up like a coiled, creased sleeve over my dick, almost like when you see a formerly obese person who shed the weight but now has loose skin.
Digestion is still bad. This is a new symptom as of around three weeks ago. I've never had digestive issues in my life and didn't even have them for the first two months of pfs. Now, it feels like I have a stomach cramp, like I've done four hundred crunches in the gym, for around an hour after eating. Sometimes the feeling is there without eating at all.
Still got the vertigo/unsteady at sea feeling variously throughout the day.
Currently focused on building my daily caloric intake back up as much as I can and waiting for the gastroenterologist appointment in a couple days.
