Welcome back.
Hitting the year mark is hard and people don't really understand IF unless they've been through it. I completely understand feeling like you have no one to talk to. My mom also wasn't super supportive when I first started IF testing almost 6 months ago, but she has come around since then. None of my friends and family have dealt with IF.
While POF sucks, the good news is that you finally have a correct diagnosis and can start being more aggressive with your treatment.
GL and if need to vent you can PM me. You may also want to post on the TTTC board. The ladies there are super knowlegable and generally there is less MUD to sort through.
