Justina, I love your honesty and your willingness to post about the difficulties a young, single expat woman faces living in a foreign country! While I've not been dragged to the ground in a robbery attempt I can certainly identify with a lot of your other experiences in Uganda. My first six months there was incredibly lonely and if my friend from the States didn't come over for three months I would have really struggled (and thankfully I had some good friends introduce me to people who I was able to build some genuine friendships with). The temptation to never talk about the struggle is legit, but you've done a lot of people a favour by letting them all know that they aren't the only ones who feel lonely/exploited etc. 
Thanks!!
