Urghhh

So we have been TTC for 2 years now and still nothing, still going through tests which is driving me crazy, but i’m starting to let other people’s BFP really affect me! I know I shouldn’t but I can’t help but think we’ve been trying for 2 years with nothing, other people get pregnant by accident and don’t take full precautions. It’s just seems totally unfair! I understand I probably sound like a psycho crazy douche bag right now but surely someone on here understands?
