Low dose estrogen symptoms and conditions

I had the mirena IUD put in Jan /08 following the birth of my 3 daughter. Since I weened my daughter in Aug I have had terrible bleeding. It started out as a period then irregular spotting then I bled most of Dec and Jan, had 6 days off then started bleeding again Feb 4. My MD sent for for an u/s and referred me to an OB/GYN. She told me that I wasn't producing enough estrogen and the lining of my uterus was thin and patchy looks like someone who is in menopause. I am 34. So I started on a low dose estrogen BCP, still have my IUD in but want it out. I have been bleeding for 26 days straight. I am exhausted, can't stay focused at work, I just thought it was due to my daughter not sleeping and working full time, but now I am wondering.....

I had my second Lupron shot this last mid October that lasts, supposedly, 3 months. So I will be 5 months in this mid December and I have to say I was one of the people who was fine with Lupron...up until now. I had and have all of the typical side effects of hot flashes, headaches, memory loss, mental fog, etc. Then I had my first ever migraine a week ago that knocked me on my butt for 2 days. My memory loss and depression are by far, by far, the worst side effect I have experienced. At this point I am concerned my memory problems and mind fog will not go back to normal, which has already adversely affected by daily life. I was one of the people who spoke positive of this injection even after reading all the horror stories but now I am beginning to wonder if they were right on some levels. When reading all the different experiences I would get confused and wouldn't know what to believe. I am not saying I would change things, the jury is still out as to whether the benefits will outweigh the difficulties, but my personal experience and symptoms have been getting worse just in the last few weeks, so that would be between month 4 and 5 on it. I could lead a pretty normal life up until recently and I'm a pretty tough person, I clean houses for a living and work hard with a packed schedule so I am not just stating little symptoms I experience but ones that actually have affected my daily life. Just being honest so you know what to possibly expect, depending on your body's reaction. That is a point to keep in mind, everyone's body reacts differently but if the majority of people are saying the SAME side effects, makes you wonder if there is a consistent pattern.

One thing I will tell you that has helped me is B vitamins regularly in your system and staying as active as possible. Write things down to remind you for the memory issues, don't over-commit to things because of the mental affects-it hits you hard when you can't follow through, and try to watch your sugar intake, which messes with your emotions. Hope this is helpful.
I would love to know from someone who has the same symptoms (which looks like almost everyone who is on it) and who is now off of Lupron for at least a few months, if the symptoms of memory loss and mind fog go away. Is my memory permanently damaged?
