Hi again,
Depression can be so wiley to make you ask those questions such as "what is really wrong with me? Why can't I just pull myself out of this??" I do know how you feel. Just keep breathing deeply... and keep in touch with your doctor. If it is too overwhelming, maybe you could simply go to a hospital and speak to someone there? Especially if you are not feeling safe alone... I mean you're not alone, we on pc are all here with you... but if you are feeling so bad that you can't cope, I hope you won't hesitate to seek someone out, even if you must go to a hospital or clinic.

The new RDA for vitamin D is around 200 to 400 IU. But if you are deficient you may need a good deal more to start...
