pez I'm sorry to hear that. Maybe in a couple of weeks you will feel differently? I know if took me a couple of weeks to get my head right after my bfn in December.
I'm the other way around now though, my friend who has helped me through my ivf is pregnant with twins, due end of March, and I have gleefully taken part where I can in her pregnancy, and revelled in every bargain she's found, each scan she's had, and it's really pushed me into an uber positive place.
As an alternate point of view: My acupuncturist is Sri Lankan and in their culture they surround themselves with pregnant friends, and family, and also pictures of happy babies are added all around the house while they are trying to conceive as they are great believers of manifestation. I.e. Surround yourself with and focus on what you want and the universe will provide.
You are absolutely entitled to feel the way you do, and if they (your friends) knew what you've just been through then they could use a bit more tact. If they don't know, perhaps you should share?
Unfortunately for some of us, it may take many tries to have a strong healthy baby, unfortunate, but true.... so given that, are you comfortable separating yourself for a time from your friends? Would that loneliness not be more hurtful? For me it would be the worst.
But, you have to be you, and feel what you need to feel, and we are all here to help you get through it. Xoxo
