Hannah, it will get easier - just grit your teeth and do a little bit every day. It is much too soon after only a week to expect great changes - the medication really needs to get into your system.
I know it's hard, and you feel you are being conspicuous, but other people have difficulties too, and may be feeling similar to you. I remember sitting on the bus one day and wondering how everyone else was so "normal" when I was stressing out with an anxiety symptom. It does get better, you have to want it to, and take life in very small bites - every small success is something to be celebrated.
