Male Baldness Info

okay heres my story
last year, i was misdiagnosised with a disease. at this point, i stressed and contemplated suicide, a body shock occured if u will.
now my hair starts falling out rapidly, i lose density by the 10%’s each month. i went to the dermatologist and he doesnt run any tests, just looks at my hair and says i have male pattern baldness. i know its not just male pattern baldness that is the case, i know stress or something went wrong with my body.
now heres the dilemma, its been a year since the incident, and i am still gradually thinning out. i am to believe that the stressful incident triggered my male pattern baldness.
theres a trichologist in my area that will diagnose my hair for 400$ telling me completely what is wrong with my hair. should it be DHT (causes hairloss) alone, i will get on propecia. should it be something else, they have treatments that can cost about 1000$ in 10 sessions.
should i pan out the 1000$? i really dont want to take propecia

Okay, well i’m not sure if i’m going through male pattern baldness. So here is my situation. My hairline started receiding when my barber cut my hair really short… looked like he shaved the whole things off. During this time i had lost a lot of weight (50 lbs) in about 2 months in an unhealthy way, ate a like a meal a day. So i don’t know whether is Male Pattern Baldness, malnutrition, or if my barber just messed up my hair. Also i’m only 16 years old so i’m really freaked out, seems like its getting worse each month. Any idea?
