Anyone else feeling resentful and frustrated by IVF process?

I am a 42F who has gone through 3 rounds of IVF had a myomectomy and now about to head into a FET. My treatment has spanned 1.5 years along with miscarriages preceding the treatment. At this point I feel angry and frustrated, we do have a few supplies embryos but given everything I have been through I can no longer be grateful and find myself wondering why I went through all of this. It’s been taxing, time consuming and expensive and at each juncture we decided to keep forging ahead. Given how hard it has all been I can’t seem to feel happy anymore about continuing down this path. My husband of course wants to have a child and seems to think I should want to go through all of this because a baby is what everyone hopes for! I am scheduled to have my transfer today and I am just so ANGRY at how much it has taken, and there is still no certainty.
