What is wrong with me?

So, I've not been having a good couple of days...I just cannot figure out how to shake this. We (my husband, and my kids and myself) are at the best point of our lives so far - everything is going so good! Yet I have this overall feeling of blah, sort of a depression, I'm not particularly sad - but I cry a lot. I feel tired, extremely tired and just cannot focus on all of the little things around me. I'm falling behind in work - never before...just don't get it. So I've been on Lexapro for about a month now, but I've also been taking sleeping pills with it. I'm thinking it's the sleeping pills that are hitting me hard now. I'm going to stop taking those for awhile and see if I don't improve. Keep your fingers crossed for me. Last night, I slept great without a sleeping pill and I feel so much better today. Yesterday, I was walking around like a zombie! So anyway...Maybe I am going crazy? Nah, I've been there already - that's not it. Oh well...Spring is here, and that always cheers me up. My flowers are starting to bloom in my yard - pretty tulips already! I love it. OK, that's a quick update - talk to you all later!
