feeling depressed. need some love

Hi I'm 28 and have been ttc baby #1 for 10 months. I know other people have been trying for longer and I can't even imagine how that would feel. I feel like I'm never going to get pregnant. I got my period yesterday and I haven't been able to get out of bed since. I honestly thought I would of gotten pregnant within a few months of trying. My sisters and sister in laws all got pregnant right away. I feel so alone, I don't want to talk about my fertility issues with my family. I did see a fertility specialist..my blood work, transvaginal ultrasound came back normal. I had an hsg x ray and my tubes are patent. The only thing they found was that was uterus was tilted to the left and it could be suspicious of endometrosis. Doctor told me to go home and just keep trying and if I don't get pregnant in 3 to six months then we can do a laparoscopy to check for endometrosis. I am convinced that I'll never get pregnant and seeing everyone around me getting pregnant is very depressing. I am happy for them but I'm jealous that I can't get pregnant. How do I stop thinking about this, I'm emotionally exhausted and it's taking over my life.
