You are taking medications for physical illness as well Psychiatric illness. As per my view, you must visit your physician first and further take consultation of your psychiatrist. Medications for bp and cholesterol need to be reviewed along with psychiatric medications. Raised bp can cause sleep disturbances, anxiety. So a detailed assessment is needed for optimisation of medication

Might I suggest trying taking 0.5mg one day and 0.25mg the next, continuing alternating dose for a couple of days then going down to 0.25 completely

Slow tapering should be done
