Is it considered kindling?

[[La...]]

Hi I just want to ask/clarify about kindling. 

I started ambien sometime June 11.  About 2 weeks into using it I was switched to trazodone by the psych. And it did not work. Then tried lunesta. Did not work tlo. 

In between the changes, of things did not work I would not sleep and so the next night I would take ambien. After couple of days try for lunesta and trazodone I ultimately went back to ambien. 

I remember one morning I felt so bad while switching ( i think I was trying trazodone that time), I was so restless/agitated with suicidal ideation and started vomiting. 

Now I realize it might have been withdrawal?  Because I did not taper, just switched directly back and forth. 

My question is was I kindled? Will I have a difficult withdrawal now because of it?

I was on 10mg pill. I was managed to get it down to 3/4 pill but only getting 3-4 hrs a night (even at 10 mg pill). 

But I really want off of it but I wonder if I am already damaged. I developed anxiety and keep vomiting and losing weight. I am sleep deprived. My body aches. 

But wonder if I'll be able to sleep again. This makes me scared
