Down on meds

I thought it might be a good idea to lower my meds. So I lowered them by myself. I did not consult my psychologist and when I told her I could see that she was somewhat upset. I am also looking for a new psychologist. Yet I keep writing checks to my old one and then I use the money to pay odd my debts. I am in so much debt right now and I don't know how I am going to get out. I am applying for disability and it has been almost 6 months since I started the process and I saw their psychologist and everything, yet they have not gotten back to me. I am still waiting. I have not told my doctor about this but I am having suicidal thoughts and I am sleep walking and waking up in different parts of the house. Once I wont up in my step brother's bed and oddly enough he sleeps in the closet so he never notices and I snuck out in the early morning. I am so confused as to what is happening. Should I be concerned? Should I tell my doctor? Maybe I should go back up on my meds. I just took a break and call my doctor and told her what I am experiencing. I am gonna go watch Donnie Darko again . 
 
Goodnight Moon.
