Hello and thank you for your question,
I apologize that you have been waiting to receive an answer for so long.
I am so sorry to hear that you have been so miserable during your pregnancy. My baby is 6 months old and I can definitely relate to some of the things you are going through.
Unfortunately, as you said, there is nothing that can be done about the overactive baby. Since Ambien is helping you, you can continue taking it as needed, same applies for nausea medication, you can take as needed. Zofran is very effective for nausea. Usually nausea goes away after 1st trimester but in some women it persists throughout the pregnancy. There are also medications which you can take for acid reflux - I took Tums on daily basis. You must make sure that your OB knows about your depressive symptoms, there are medications available (safe during pregnancy) to treat depression. Once the baby is born, depression may get much worse (called post-partum depression) so please address this with your OB early on. Otherwise it is a waiting game, as soon as the baby is out you will feel better.
In terms of your feet...it is possible that you have a fungus infection on your foot which is not responding to creams. Sometimes you need oral medications to treat a moderate-to-severe fungal infection. But since there is no definitive diagnosis, you might need to get a biopsy or a scraping from the foot to confirm presence of fungus. If fungus is not showing up, biopsy will direct the treatment. I would recommend that you see a dermatologist for evaluation but in the meantime, I would recommend that you use Eucerin ointment (available over-the-counter) on the foot and cover it with a sock (especially at night). This will help trap the moisture and provide some relief from the cracking and scaling.
I hope you find this information helpful. Please feel free to follow-up with any other questions you might have.

Hold on tight, your misery is temporary. Its all worth it when you see your baby for the 1st time.
