EMDR Therapy. Will this work in my case?

I am at a point of my life that I really want to take care of my issues, so I can finally life a more normal life.
I was referred to EMDR therapy for all my general problems. Light depression, unhappiness, low self esteem etc.
The person thought it had to do with some kind of trauma I went through.
I have indeed been in something yearsssss ago, not too big, but at the emdr session, I wasn’t really feeling anything.
Also I cant even say what score I give it from scale 1 till 10. It was so long ago, that I think, yes it was sad/crazy but that’s about it, I don’t feel much for it anymore.

So how is that supposed to work with emdr, does that mean this wont work for me?

How can emdr help me with my general problems if I can’t think of a real trauma?
I mean she keeps on asking me questions of how I felt about it, what I am thinking etc, but most times I didn’t have an answer to that. I wants really thinking, just spacing out while she did the finger movements.

Is EMDR possible to do without a specific incident/trauma.

Any advice?
