my voice is very soft and high
i thought it was due to my sinus problem, that mucus gets saturated around vocal cord and so voice becomes soft and high, but then i was surfing on internet, it said high pitch voice can be caused due to low teststerone,

although i got beard and moustach, have pubic hair and testicles size is normal, i think the testosterone didn't reach my vocal cords,,
i try so hard but i can only speak in a lower pitch with making a weird face and twisting my neck, is that sane infront of people?
and i m already 18 now, but have no frnds becoz my voice is high, ppl say there's something wrong with my voice, everytime i talk, i m sick of this!!!

pliz i need help, is there any exercise or medication to deepen the voice or increase testosterone??
are there side effects?

pliz i m going college after 1 month,, and if i have a deep manly voice, i can atleast hope to have frnds there,
i want my voice really deep and hard

thx
