Please Send Advice ..

i have pcos. i was diagnosed almost 3 years ago. For the first two years since diagnosis we were heavily trying, with metformin & clomid. we did several cycles with clomid until we worked our way to 150 mgs which showed on the ultrasound that i would ovulate. still nothing. tried 150 again for two months and nothing. I started to feel like i was changing. so i stopped. for the last year i have been taking only metformin. Recently i have decided i still haven't went back to myself since the diagnosis. i'm always sad, upset, angry. i think it stems from my diagnosis. i want children badly. i want to be normal so badly. but most of all lately i just want to be happy again. i have decided that i am no longer going to let other people effect my mood or my day. i am going to be happy, positive, loving, caring, no matter what. Day one of my new life, and every one around me is talking about pregnancy, and how they accidentally got pregnant or how they're feeling during their pregnancy and how whoops i'm on birth control and still got pregnant. and it hit me. again. sad. mad. angry. hateful. i thought to myself what is the problem ?!! it's only day one ?!!!.. all night last night i thought about this. How in the world am i supposed to not let this get me down? how am i supposed to be happy for my friends and family around me that are always becoming pregnant. how? how do i hear about others & their precious little miracles & not let it ruin my whole entire day? How can i be happy again? i want to be myself. i want to feel happy. All i do is siclude myself from the world & sit alone unhappy and angry. blaming the whole world for something that happened to me. something i was born with. i need advice. i literally want to be happy again. i even tried to pretend in my own mind that i didn't want children. it doesn't work. nothing i know to do works. please help.
