Thanks guys! Yeah Eileen I definitely want to try to think of this as "activity I enjoy" not "activity I have to do." If I think about it the second way, I will beat myself up on days I am just too tired to do it, etc, and there's just no need for that.
On another note, I just went online and spent some money on vitamins! Lately I've been good again about taking my vitamins every day -- right now I am just taking a multi and a high-dosage B-vitamin complex. But I'm running out of my multi.
So, I bought DHA online, which is the best omega-3 to take and has been shown in clinical trials to improve memory and brain functioning -- cool -- plus I bought a carotene complex, vitamin C, and a really good multi-vitamin. So now hopefully I'll be the healthiest girl ever!
The B-vitamins already have been making a difference. I can tell if I even miss one day of taking them, the effect on my mood is so profound.
I actually wonder if I have a B-vitamin deficiency which might lead to some of my issues with anxiety and depression. I avoid prescription meds, refuse outright to take a daily SSRI (because I am bad about forming habits and am deathly afraid of withdrawal on the days I am sure to forget to take them), but I'm all about natural healing.

Today's bike ride has inspired me! Maybe I will even start eating healthy foods!
