I need help!!

I have a 5 year old daughter and I have been trying since she was almost 2. I have been depressed and went through so much. My husband and I have tried so many things😢 I have went down some really dark roads trying to blame myself for not being able to conceive. I have went to doctors and they do all kind of test and come back with nothing is wrong but I am young so they don't want to go to the extreme they tell me to keep trying. I am 23 yes I'm young but my heart is set to being a mother. I have came to a point in life were I don't know what I'm doing wrong or if god is even listening. I can't talk to my friends because they don't understand, every time they try they succeed. So maybe some advice from you guys would help. I have just started taking the Geritol today so maybe that can help. I did go to the hospital a while ago and they found that I had follicle cysts but they said it shouldn't prevent me from concieving . I look for something to blame but there is nothing :(
