yes, yes, yes.
My heart goes out to you and all mums feeling this way - I know, and it can be quite overwhelming!
Well, as I've had periods of my life like that and have found many ways to counteract the grumpiness/sadness/wondering how "they" manage "better", and so on...
Apart from contacting me as a client! (i'm a personal trainer, life coach, nlp practitioner and healer)

i tried these, which worked for me, sometimes:
allowing myself to indulge in crying,totally
setting a time limit for above indulgence
pretending that i could see myself from a distance, and having more compassion for myself as a result of it (as well as having a laugh)
remembering that it's a phase - i'll get thru it as i've gotten thru other challenges, and it'll be great on the other side
Reiki healing
appreciating nature
appreciating how wonderful my body is coping with things
feeling grateful for . . . (fill in your own)
joining a mother and baby class - for absolutely anything!
doing something for myself by myself (eg work, hobby, pamper, therapist, reading)
ignoring the other mum's fantastic-ness
remembering that practice makes perfect, and remembering that perfect is different for everyone
remembering to look forward to ...(fill in) and do something towards it
helping someone, for no other reason than a diversion
laughing at myself
physical exercise
doing something engrossing and creative eg.mosaic tiling,knitting,sewing,dancing,playing music,painting
GOOD LUCK discovering your own
wishing you a lovely day too!
