Hi Michi,
Sorry to read your story. As @Dubya_B says, many recover without intervention.
Please, do not start scouring forums for advice on how to fix things. The irony of most advice given is that those offering it are rarely recovered themselves. That is to say, why are the people who haven’t fixed things telling you how to? Why haven’t they been successful if they have the answer? Also, beware those who might try to sell you something or those who do not have a plausible story with enough history to back it up.
In general your symptoms are not uncommon here. The general advice is that a number of substances bring people here with some regularity. Anti depressants, hair loss treatments, accutane are the most common, there are others including skin creams and health supplements.
At this point it’s probably fair to say that you have a vulnerability to all those substances. We have generally seen that subsequent exposure to those substances can result in catastrophe. Avoid them.
Also avoid substances which are 5ar inhibitors. This could be in food or vitamin tablets. Check hairloss websites who offer tips for foods to eat to stop hairloss and do not eat them. They will often be 5ar inhibitors.
This is a lot to take in and at your age it is a hard thing to deal with. Rest as much as you can, avoid stress and don’t do anything rash.
If you are planning on taking advice from an Internet forum, try to take some time to think it through. There is a lot of misinformation, delusion and lies out there. People can seem very knowledgeable, when in fact they are merely repeating things they’ve read but don’t understand.
Do what Dubya said and get your symptoms reported. This is a real problem, one that you have because too few people speak up. The more we can tell the world this happened, the more that will be done about it.
