Absolutly devastated :(

Another visit from lovely Aunt Flo. Don't think she's got the message that I want her to take a holiday for 9 months?! Been ttc nearly a year now. Had my mirena removed on 23-06-13. Doctors don't think there's any problems,so why on earth am I at the year mark?! I always get upset when af arrives but never like this I feel physically exhausted & tired of trying. I might just delete everything to do with ttc,I'm obviously never going to get pregnant. It's never going to happen to me I'm never going to get a BFP. Feel like Im being punished for everything bad I've done in life. Why is this so hard?! Ttc is meant to be one of the most natural things in the world yet it's so hard & takes everything out of you. Not sure I can do this much longer. I'm never going to get pregnant. Feel such a failure. Normally I just pick myself back up & start fresh focused on a new cycle but  today I honestly feel so drowned :( sorry for the rant
