Take some gas money and buy some vitamin D3 in the largest IU available and get some high potency B vitamins, esp niacin. Green leafy vegetables with lots of folates…spinach, collards, kale, that sort of thing. Good high quality protein, sunshine and exercise. Within hours after taking 500,000 IU (safe - Drs give shots with millions) you'll feel better, within a week after the B's, protein and folate you'll have a new outlook. Exercise even if it sucks.
Take control and steer your life even if you don't what you're doing…control is empowering…failure is a part of life. Drifting is powerless and demoralizing. Set some small short term goals and work on them. Bigger ones too.
We're all tired. You're in our prayers, Anon. Peace to you.
