Depression and miscarriage..

So, my husband and I have been trying to start a family for 2 years this month. I found out I was pregnant December 11th 2015, we were elated! We saw our sweet baby's heart beating at 6 weeks, went in on January 11th 2016 8weeks and there was no heartbeat we had lost our sweet baby.. It completely broke me.. I have PCOS and was on metformin and letrozole to get pregnant but it took 19 months to work. The medication is no longer making me ovulate so we're taking a break until july in hopes it will work again. I guess I just really need advice, what do I do to keep my mind off of everything? I have been super depressed.. a friend of mine had the exact due date as me and she almost rubs it in my face that she's still pregnant.. any words of advice or encouragement I'm grateful for.. I feel so low :(
