Lesley symptoms and conditions

Can anyone tell me if I'm going mad or if it's my Mirena?
I had a Mirena for 5 years (inserted in 2003), then had another one put in in October 2008. I have no periods - great. BUT I feel absolutely dire. I have depression and anxiety (I feel like I'm seriously going CRAZY sometimes, to the point where I'm worried about getting sectioned cos I can't handle the overwhelming feelings), I feel like my head is full of fog, I have dizziness, when i stand up I feel faint, I am crying (I usually never cry), I don't feel like i can cope with anything except the barest minimum to get myself and my family through the day. My 12-year-old son asked me if i have early-onset Alzheimers because I can't remember anything. If I was feeling ok I'd find that funny, but it broke my heart.
My previous Mirena was fine, I felt ok. Please can anyone help me?

Anyone coming off of Celexa feel free to email me. I have been off for 4 or 5 days now and I don't have enough time to write down what I am going thru.
Bad dizziness/wavy when I turn my head.. clenching teeth..my right arm is aching.. no idea why or if it has anything to do with this...
moody...feeling I can cry and have.. at almost anytime.. headaches behinf the eyes..
This is hard..not to mention no libido whatsoever...
help?

Does anyone know how long does the sexual side effects of Celexa wear off after I stop taking it.

I started on it in June 2007, by December, I had gained 20 lbs, was out of breath most days and was weak all over. Had general sore muscles and felt out of strength. Been off now 5 days, strength is returning and am feeling much better. No weight loss yet but at least I feel much better. Sleeping was not affected one way or the other.
