so how long did the dread shed last?

because I cannot deal with this much longer. my hair was a little thin on the sides when I started but it was manageable but in the last 5 weeks that i've been on 2.5 of oral minoxidil, it has lost so much volume. I can actually see my ears through my hair and i cannot stop crying every time i see it in the mirror. i'm trying to trust the process, but it feels like i'll end up with nothing left at this rate.
