I went through the same thing.
The reason we are preoccupied with something that keeps gnawing at us is the mind likes certainties. The unknown (when will my hair grow back, when will the cure be out, when will this be over) causes mass anxiety.
You gotta train yourself to cut it out. Think long term...think..yes i'm losing my hair, but if I don't do well, not only will my hair suffer, but also other aspects of my life, my career, my future. In the end, with incessant checking for cures, if there is none, not only will I be bald, I will also have fckd up in school, feel even worse than before.
Cost benefit analysis.
It works. I come on this forum once in a week, check the notifications, go about my business. Nothing I can do will speed up or slow down the process of a cure for hairloss. All you can do is use existing treatments we have and hope for the future.
There's a flowchart I can't find but its something like this:
Is there a problem? (Yes/No)
---NO - you're good!
----YES - is there something you can do about it? (Yes/No)
YES - then do something about it
NO - then stop worrying about it.
