Help please

I've only had floaters for a few days, even though I've already been to the doctor and they told me there's no damage to my retina yet, I live with the constant fear that it could happen at any moment just like the floaters happened. I have them in both eyes and when I think too much about them and this, I get really depressed, I get a knot in my chest and stomach and I fill up with anxiety.

I'm relatively young, 27 years old. Tell me about your experiences, have they gotten better, worse, what have you done to feel better.
