I know how you feel (at least this sounds familiar). Somehow lately I’ve been able to get over the “drained”-moments. Since I’m an extravert and get a lot of energy from people I go talk to people that have a mind for business or are just supportive in general. Also I read quite a few articles of people that are doing the same thing. You could call it my improvised support group I guess. Don’t know if that helps you, but I hope so.
