What do you think about me having lice for the past 7 years and not knowing what to do anymore?
Are you joking? Have you tried to get rid of the lice?
I saw a doctor, and then I had appointments with some other people who claimed they could get rid of lice.
If you have had lice for seven years, then you need to see another doctor or take more extreme measures than you have so far. Lice are unsanitary, and you are probably spreading them to other people you are around. You need to take the problem more seriously and work harder to get rid of the lice for good.
I can't stop them. You don't understand how hard it is.
You need to take a lot of time towards this, because seven years with lice is a very long time and you could have infected thousands of people. You're going to need to really strap down and take care of your hygiene until you do stop them.
