Feeling "blue" on tamoxifen

Hello there, has anyone else felt flat, down in the dumps after starting tamoxifen?  I have been on the little white pill 20mg for 2 months now, and my anxiety levels are also quite high, but I do have upcoming scans and alot of worries still.
Any pearls of wisdom for helping to overcome my flatness?  I exercise daily, trying to eat as healthy as I can. In all honesty I do miss a little bit of alcohol to help me relax!!
Thanks ladies
