Hi I Have Recently Stopped Taking Sertraline, Serquil, Trazedone And

Hi i have recently stopped taking sertraline, serquil, trazedone and inderel. I had been wanting to come off these medications for quite some time but my next appointment with my doctor is not until March. I got a bug and had diarrhoea for three days and didn't eat or take the medication during this time. I have recovered from the bug and found it an opportunity to stop taking my other medication as I had been days without it already. Now I am experiencing a strange feeling every few minutes when I standing or moving around. It is a sort of dizziness and loss of circulation in my hands and body. I feel as though for a split second I could easily faint but then the feeling passes. It is a horrible feeling and is constant throughout the day. It feels like something definitely is not right. I am not sure if it is due to me coming off the medication. Though it only started to happen days after I had recovered from the bug and come off the medication. Please help. Thank you
