I agree with most here that only you can pull yourself out of this funk. In time things will get naturally better on their own, thats the way our emotions ebb and flow. However if you want to have a better grip on calming that flow and creating a happier life, you WILL have to take action.
I wouldnt concern myself with all of the "finding a meaning" and other self help concepts out there. This actually can work against you.

So I have a few questions
1. Where are you living right now?
2. Do you have an income?
3. Love life?
4. How much completely isolated and peaceful "you" time are you getting?
