help when not conceiving..

ASHLEY
we have been trying to conceive a while now and every month when AF comes I just feel a depression and I feel like I've failed one of the things I'm supposed to do in life that might sound strange..especially when it seems everyone around me is pregnant most of them with their second or third baby. has anyone had this issue and is there people or resources to talk to about this I feel like my husband dosent get how I'm feeling and he stays positive which I love him for but I guess my brain isn't wired that way.
