I have been investigated twice for PCOS (10 years apart) and both times I was found not to have it so don't stress about something that may not come to pass.

Children can also hurt you with their touch and their words, and some frequently lie so please don't go down that track thinking you are going to have some perfect child who is going to make you complete - they simply don't exist. Children and adults are human after all and all humans have their faults - some more than others and you can never predict how someone's going to turn out.

Like Charlotte said you must love yourself before you can love another. I'm also thinking you've been hurt somehow in the past. Perhaps some counselling could do you some good.
