If I were writing to myself, when I was about your age, it would be to say:
You will be happy when you get to 30+, things will work out in life for you on so many levels during your 30's and especially 40's, so don't be concerned life sucks hard at the moment, have for the last few years and will for the next few I know, but stick with it, things will work out in the end. The issues you have at the moment will build you and make you independent, tough and resilient enough to accomplish what you will. The gain is worth the pain.
