never felt so low

Anyone feel so low they don't even know why there carrying on with life and feels like pregnancy isn't ever going to happen. I had my first mc in October 2016 and been trying since then! My mc changed my body so much I was on a 28 day cycle now I'm 30/34 šŸ˜­. I don't know what is wrong with me, everyone around me is pregnant or falling pregnant even a friend who had a miscarriage the same time as me!! I feel so depressed and I feel like it's taking over my life all I crave is that 2nd child! I know most of you will think well she's got 1 child I'm being greedy but I can't help the crave I get for it. What else can I do ladiesĀ
