Dealing with anger and resentment

I'm 34 and ttc #2 for 18 months now. I'm at my wits end. I know I'm pms'ing really bad, but lately I'm just dealing with so much anger and resentment over not getting pregnant. Anyone else feeling this way? I took up running and just run my anger out, fighting back tears over this baby that will never be. My daughter is 4 almost 5 and I just wanted to give her a sibling. I'm angry with God, angry with my body, jealous of pregnant friends and family and those that have 2+ kids. I'm so tired of feeling this way. Thanks for listening to my vent and if you ladies have any advice I'll gladly take it.
