I'm so fed up of my tiredness over powering me! 
I keep snapping at both dd's (2 and nearly 7months) and my dp. And more so when I am feeling so tired and low and snappy I then kick myself in the ass about taking it out of them. Then I start thinking I'm not good enough to be around them etc.
Take last night. I was so tired. It to bed about 11pm... Just got into a sleep and dd2 wanting feeding. But she she wouldn't latch on and I just snapped and started saying to do oh maybe I can't cope!!!
Tiredness is the culprit I think. And lack of good diet. I am usually so chilled and patient. I had my first period a few days ago since having dd2. But couldn't be that. I'm just fed up of having these minority days out weighing my good days. I know everyone has bad days and this is mine but I hate shouting and snapping at my dd's!
Two and 7months can have challenging days obviously. I just don't get where my patience has gone???
Sorry rant over!
