2nd what Zaya said and would like to add that what I think may be missing is a purpose. This can be a job venture, a dream you have/had, wanting to keep in touch with people and have them over, whatever you can think of. Is there anything that gives you a drive to keep going? I kind of lost mine for a bit but I'm starting to find it. What you describe was me 2-3 weeeks ago before I got my job. I was technically happy but no purpose so what am I doing sort of thing. So that's why I ask. Other than that I hope you can find your happiness again OP. Come talk to us more if you need.
