With the right to vote given to you, you should definitely vote. Do you want to be represented fairly? Then vote. If you really don't care, then don't vote. You'll be shunned as someone who has no right to complain about UPS because you chose to be indifferent though.
If you need to be medicated that's your business and a lot of people are on meds so don't feel bad. I wouldn't air it out on a wan site if I was you though.
