What can you do when you hate how you look and are too unattractive to date (pic included)?

may be do the reverse, just not care about being confident, just focus on things you enjoy doing, what ever you are pionate about, don't worry about dating. You seem to like the outdoors, yosemite etc, so just focus on that kind of stuff instead. But I do think you need to embrace your height at least, perhaps get into some fitness diet routine.
