Fighting Seasonal Affective Disorder

I realize it has been a while. I'm sorry for that.
I think it's time to admit that I do have a problem with Seasonal Affective Disorder and I need to address it.

If you're not familiar, Seasonal Affective Disorder (or SAD) is a type of depression which is directly related to the changes in season and the levels of sunlight a person receives. Symptoms are different for each person ranging from losing interest in activities, having low energy, sleeping problems, difficulty concentrating, feelings of hopelessness or guilt.

I've always had a winter-blues kinda way about myself, but as I've grown older, this issue hits harder. Can you believe the only reason  I haven't blogged is because I didn't want to turn on the computer? I mean how low energy can you get? 

But it gets pretty bad and has consistently gotten worse. I plan to really get to the root of this problem and figure out a way to fight through from November to April.

Do you have problems with SAD? What do you do to fight it?

What do you do?

Ok, so  today I fell into a tricky trap and I don't know what you other mama's do in this situation.

We had to go to the Walmart and while waiting in the check out line, Bun saw a tiny Elsa doll. It was cute and reasonably priced. It would be perfect for a Christmas stocking stuffer.

Except I was caught putting it on the conveyor belt. Then Bear saw his sister was getting something and he wanted something too.

Well fair, is fair, right. So I bought him something too. And then I felt I couldn't not give them their toys right away, since they'd caught me.

Augh! Even though I had no plans to get them more toys and now I'm beating myself up for spoiling them and wasting money I should be saving.

Ahhhh!!
The guilt.

Seriously, what do you do in this situation. Should I have left Elsa and come back to the dreaded Walmart later on the rare chance I will be without children? Should I have lied and said the doll was for someone else? What would you do?

Help? I'm a terrible mother.
