Mirena and tremendous pain

This site has been a god send. I had mine placed 2 weeks ago and its been horrible. I've been telling myself that everything is going to be fine, but its hard to believe that. Getting it put in put me in tremendous pain. I could barely walk and i had to work a 10 hour shift an hour later. After 2 days the pain went away but i started to notice random bouts of depression. Ive been a totally different person, Im happy and laughing one minute and the next im in tears over nothing! What made things worse was I was starting to feel nervous and shaky on top of wanting to cry all the time. I figured it had to do with Mirena because ive felt this way once before and that was when i tried the depo shot. Within the last few days ive noticed an unusual discharge and itching. Ive been thinking it might be a yeast infection but i have never had one. Its just one more thing im contributing to Mirena. I dont want to get it removed because its nice not worrying about pills or condoms but at the same time I think Mirena is making me crazy. Reading these posts really helped me regain some of my sanity. Ive also heard from many people who used to have an IUD that as soon as they had theirs removed they got pregnant. I know to use condoms but i dont trust them, accidents happen.

Many strange things have been happening to me for the last year and a half, that I did not ever experience before. I just turned 38 years old. I am now suspecting these are side effects from the MIRENA. I want to get opinions about what I'm experiencing and what happens when it's removed.

The most profound thing is the feeling of being in a mental bubble. Even though I'm aware of it and I try to be alert, I feel cloudy minded and can't even rely on myself to remember things or commit to things because I never know how I will feel when I wake up each day. Some days are okay while others are completely LOST because I may have struggled to sleep the night before, sweating and soaking my pillow case and waking up with a rapid heart beat, panicking for no apparent reason right out of sleeping. Or, I'm irritable due to discomfort which takes several forms like these:
- major moodiness, like feeling totally peaceful one minute and then something small triggers me and I'm angry for hours, later realizing that I was overreacting
- visibly shaking hands, especially when I drink just 1/2 cup coffee.
- increased oily skin and acne on face, back, shoulders and even in ears, along with thinning hair around face
- fatigue and stiffness in the morning, so it takes me forever to get out of bed
- off and on fatigue that has me uncontrollably dozing off during the day
- bloated tummy (visible), gas and menstrual cramps in no predicable pattern, but I never go more than a week without these things
- strange libido, one day I wouldn't care if I ever had sex again, the next night wake up horny as heck at 2 am
- ears ringing, jaw pain, mystery pains in back and joints regularly

All along I've been assuming these odd things were stress and age related but the more I think about it, there's just too many things, and these things don't necessarily represent the stress of a typical stay at home mom.
Sure, I have had stress and anxiety in the past, but they could always be connected to something large going on in my life. Now, the anxiety and moodiness hit unpredictably and indiscriminately, it seems. For a long time now I feel like I'm a total mess physically and mentally, even more so because I realize something is wrong
I am pretty sure as of right now that I should get this removed. If the symptoms go away I'll then know what caused them in the first place.
I am wondering what happens upon removal, will it also be a roller coaster of physical and mental anguish???????? How long will it last?
