Don't overthink it but just try to avoid using that word even just a little, even just when talking to yourself.
For me, when I was constantly thinking to myself "I need some help, I just need more help" it was adding to my feelings that I was failing as a mum. Now I think "I just need DH to do xyz" or I think "the KIDS need DH to help with xyz" and this makes me feel like I am doing ok. I am just managing the normal struggles of parenting and co-parenting. I don't need help, I am just working in a partnership. It has really helped me. Good luck. X
