Major anxiety

Hi Mamas! I have 1 son whose 3 and have been ttc since last August after a MC at 10.5 weeks and a chemical two cycles ago. We have started the IVF cycle, my meds are ordered and suppose to start them next week the 17th. I’m feeling so anxious about the whole thing- the amount of injections, the retrieval, the cost as everything is out of pocket $23k estimated. Part of me is like do I just not go through with this and Im lucky I have my son but other part would love a sibling for my son. I’m also so nervous something bad will happen. Ugh how are you dealing??? I am seeing a therapist but have only been 3 sessions and I wouldn’t say it’s helping yet.
