[TheCapeGreek]

Focus on getting out the house first. Experience the world. Try meditation. Exercise - not for muscle or aesthetics, but because of the endorphins that will make you feel better.

Don't set goals. The only goal should be to undertake these actions regularly. Life might still feel intellectually empty while doing these things, and that's okay. The point here is to start with your body as it'll feed your mind and you might start to feel a bit better.
