But theoretically, E2 would pool and increase with each shot because it is not being absorbed by the receptor, that is why the congenital estrogen insufficiency patients all had very high E2. Also, estrogen increases SHBG, so if estrogen is not working on the cells you would see very low SHBG https://www.ncbi.nlm.nih.gov/pubmed/10439005
Also, I went through nursing school, I know how daunting it is, I am in school for my DNP currently. If you are surviving nursing school, you are doing fine man. I'm not saying you aren't struggling, but anxiety can manifest some nasty physical and mental symptoms.
E2 would not pool. Unless your liver didn't work. E2 has a half life of 12-15 hours. Before my issue, nursing school was a breeze. Now it's so difficult because I have no drive and focus.
Please do pay attention to what I say about myself before this issue. I never had anxiety and depression. I never had ANY of these physical symptoms when there's over 12 different symptoms. All started when I crashed my E2 to zero.
Im telling you, 5 months ago if someone told me what I'm telling you i'd say the same thing as you are. It's psychological. It is CLEARLY not. I'm having serious issues that are directly related to crashed E2 from months ago.
