Rat sized head lice overtaking my head

Description: Let me begin this by saying i've seen severe lice infestations on youtube. i always thought to myself, "how can they let it get that out of countrol and not even feel them?" i am currently suffering from a massive head lice infestation and you will be in total shock when you see just how humongous these horrible pests grow to be-i had no idea the could get that huge! i've tried every remedy out there and nothing will make them go away. i show you the nauseating insects up close and personal all over my scalp and hair as i comb and blow dry my hair to no avail in an attempt to remove them. i wouldn't wish this on my worst enemy!
