Deep brain stimulation related. Less?

I've been having this issues of tremors for last 9+ mths. Tried diff medicines from tremidon, pacitane. Inderal la etc to lorazepam inj. Nothing is working. My mri and eeg are normal. My neurosugeron has suggested me to get dbs done at the earliest as this is putting pressure on different parts of my body. There's minor prob in spinal cord, there uro related problem which the uro surgeon believes is due to brain nerves. Also I've recently started developing epilepsy. I fall down I get unconscious at times hit different stuffs. Will dbs help me in that too? Also I'm a patient of ulcerative colities so taking treatment for the same and patient of depression. I heard that dbs helps in depression as well..so ultimately should I go in for dbs.? Also the cost is pretty high the only thing that's pulling me back. Where can I get it done for less? I've even been referred to movement disorder specialists and what not. Tried everything but simply of no use., please help.
