At the end of the tunnel is there a light or is it just dimming slowly?

Have you ever wondered what life would be like 10 years into your marriage? Well I always thought that we would be happily married with 2 kids and a house. Reality is a cruel bitch! 10 years married and we have spent the better part of our 10 year marriage trying to have a baby and going through infertility treatments. I fear that now we have to accept the truth... we cannot have children and must scrap the plans we had but the question remains can we survive just the two of us? Is there really life after unsuccessful TTC? I want to say that we can and there is but I am starting to fear that is no thte case. I have lost all interest in BD or any kind of D!! He is miserable and therefore I am miserable... I am scared that without children we will soon realize that we have nothing in common anymore and will grow apart. After everything we have been through I have always thought and believed we could overcome anything and jump any obstacle but I am just not that sure anymore. I think about our future and I am not seeing that happy future I always had seen before, I am scared to even think about how lonely our future is going to be. I have always had hope.. I believe there is still hope but what is really scary is that lately I have been having some very odd things going on with my body. I am having hot flashes and moodiness and NO and I mean TMI HERE LADIES ...... NO LIBIDO! Get away from me isn't even close to what I feel... I hate my life... it is total crap.. i have crappy feelings and feeling of dread and sadness constantly! I do have a dr appt this week because I have had an MIA AF for the past 7 or 8 months... so I am thinking that has something to do with it (lack of AF), maybe its a hormone thing . BUT I am worried that I am going through perimenopause. IF I go through menopause I have nothing left... no hope.. no faith nothing. There is nothing in this world more scary to me than that...
