Jennifer, your case sounds a lot like mine. We're starting our 5th year of TTC with undx IF. Though my recent 2nd opinion said he suspects, but can't prove, that I have an egg problem.
I am lucky in that we're only limited by how much emotionally we can handle. I have insurance that pays 100% with almost no limitations (the ones they do have don't apply to me). My DH and I actually would not be doing another cycle had the last one not resulted in a PG. We are only doing this because we feel like we came so close last time, how can we not try again. But honestly, we are both coming to terms that this may never be something that was meant to be for us. I'm pretty sure, this will be it for us. If we are able to get a FET out of this next fresh, we'll do the FET. But I'm pretty sure we will not continue on after that. I am beginning to resolve that this is not meant to be and am starting to change the way I envision our future. I find myself talking less and less about what our future will be like with children and find myself talking more and more about what we'll do in a future that does not include children.
So, your feelings are completely normal. I also am in this alone. My family doesn't know anything about this and I have only 3 very trusted friends who know (and my boss). My boss is very understanding and compassionate, but I only talk to her about it to the extend of the time off that I'll be needing. Of my friends who know, only 1 am I able to actually talk to regularly about this. 1 is male and would be uncomfotable having these very personal discussion with me. 1 is sympathetic, but she doesn't understand and I don't get much comfort talking to her. The 3rd, her sister went through IF. While my friend herself has no problems getting PG (2 of her 3 were surprises and of the 1 that was planned it took all of 1 month of TTC), because her sister went through it she has a better understanding of what I'm going through. If I really need to physically talk to someone, I talk to her. However, for the most part, I don't talk to anyone physically. I message on this board for the most part. I've formed some friendships from this board and have become FB friends and email friends with a few ladies that I met on this board.
If you really feel like you need someone to physically talk to, look for a RESOLVE meeting in your area. You also may want to check out this book, Coping with Infertility: Clinically Proven Ways of Managing the Emotional Roller Coaster by Drs Negar Nicole Jacobs and William T. O'Donohue. I found the book very helpful in learning how to cope with IF. Good luck
