Im not entirely sure Im posting in the correct place, but Im sure you lovely lot will let me know if it should be moved. 
My DS4 is 15 months old and I think I am suffering from undiagnosed PND. I have really struggled with things and although I am in a better place now, I still struggle with my patience/temper/feeling of self worth etc. etc.
I actually I think, looking back, that I had it with my first 10 years ago and have never really gotten through it...mostly because I convinced myself that everything was ok. After I had my second child, I did go to the doctor and talk to her about it, I had 2 children under 2 and was working full time, Dh at this time was a stay at home Dad. The Doc thought I was just a tired wee girl and to get DH to do more and I was to do less
at that as at that time DH kept a better house than I ever did/do and I had very little "houseworky" type stuff to do, maybe help put away washing, but not much else.
Anyway, fast forward to now, I only work a few hours a week and Dh works full time, a situation that has suited us both for quite some time. As i say I really struggled when DS4 was born and still do but thought I had got over the worst of times....there was a point where I could see me spiralling and I told my DH that if I couldnt stop it I was gong to have to go to the doctor and perhaps get some AD's.
I had thought I had managed for the most part, until this morning, due to a botch up with babysitters and my DH having to attend a funeral....I had to cancel my hair appointment again....cue a bout of sobbing that started at around 10 this morning and hasnt really stopped....I look terrific it has to be said 
I wont bore you with all the ridiculous thoughts that have gone through my head since then (none of them serious I hasten to add)
After all of the above I will finally get to my WWYD....I think I need to go to the doctors and obviously I need to get DH involved so we can sort out how we tackle this, but he is of the "mental illness is a load of bollocks" camp and im not sure how to get past this.....
Am I just tired?, should I go to the doctors?, my husband will be supportive of me, but it wont be fully if he doesnt really believe there is something wrong.....
I dont know, me head is such a mess....thank you if you have managed to the end and apologies if any of it didnt make sense.
