Been prescribed a b12 injection by my dr. i have probs with mood, anxiety and depression and have been on several meds..he thinks the b12 will help.

If your B12 is low: It may help you energy level

Be hopeful: Especially if you'd tried other meds and still need something more, give this a really optimistic try. All B vitamins serve the nervous system and B12 is a energy/attitude lifter. Also, remember that ALL research shows that good psychotherapy (trust/confidence) optimizes gains. It can even help you lower doses and shorten use. You just need o find a good fit. Best!
