Nightmares Again (Ultra Loud Sigh)

I am known for extremely active motion while sleeping. Once asleep. I have fallen out of bed this morning and my husband found me trying to get into the closet. In the dream I was trying to get out of my childhood bedroom in our old family home.
I had a visit from my mother today. I view this dream as a cry to get out of the caretaker role that I am in with her. I view the responsibility of caring for her as part of the depression that I am in. That sounds selfish, but the subconscious does not care it just wants out. I want to get out of the depression and I view any responsibility that takes attention away from trying to heal myself as taking away from me. From my health. That is one reason I ended up in a mental hospital late last year.
But I can't give up the care of a 91 year old that needs me. So I have nightmares instead. Makes sense to my waking mind. To my subconscious mind, which is just trying to protect me, it makes sense to run way and shirk the responsibility of her care. I can understand what is going on. How does one take care of the situation when one loves one's own mother?and subconsciously one wants to stop the stress that is part of the cause of the problem? Ultra loud sigh (Again)  

Post Hospital-Again

I was in the psychiatric ward again. The cymbalta was not doing the whole job. The stay was from 12/27/11 to 12/31/11. They gave me risperdal at .5mg twice daily. This was wonderful at first. But as I reentered the outside world, my sleeping took a nose dive. The anxiety increased 10 fold and the allergies magnified. I checked the air filter in the AC system and it was filthy and I replaced it last night.
At one AM I had not slept again for the second night. I went  to Walgreens and got some melatonin product that is called Sweet Slumber made by Schiff. This did pretty well until I woke up with a racing heart about three AM. It took about 5 minutes for it to calm down and I went back to sleep. This is scary enough for me to seek medical advice. I took the Sweet Slumber because the pharmacist said it would be alright to do so after I told him about the antihistamines and antidepressants. When I got home the inside label said that depressives should not take the product.
I want medical advice. I need sleep and the allergies are keeping me up, agitated and irritated. I will go to the allergy doctor to day for a shot and I will move the next appointment to the next available date. I must have relief!
