IUI Anxiety

I’ve done two natural cycle IUIs that were terribly timed by my last clinic and both failed. I made the decision to start fresh with a new clinic. New clinic is telling me that because they weren’t timed well or medicated that they didn’t really stand a chance at working for us. Thing is I already have anxiety and all of this stuff surrounding next steps with treatment is making me freeze. I have no idea if I can mentally, physically or emotionally go through another IUI. They want me to try at least 1-2 medicated IUIs, but I’m just not sure I can handle it. How do you take next steps with treatment when you have severe doubts? I just need this to be over with :( anyone else experiencing anything similar?
