Is this postnatal depression?

[pinacolada22]

The past week or so I have started feeling frustrated towards my 4 month old baby, when she's crying or won't sleep. Since she has been born I have never felt this way, only recently.
I don't want to feel this way but I don't see a way out of it. I think its a combination of the sleep deprivation, living in a messy environment and the pressure of my job that is causing this. I'm a single mum and no family nearby.
If I go to the GP for help, what can they even do?
Also, will switching to formula help me mentally? Because I find breastfeeding very difficult atm.

Didn't want to read and run.
It sounds like you have a lot going on with being back at work, single parenting to such a small baby, breastfeeding... Sleep deprivation and exhaustion definitely make everything feel tough.. is there anyone who could help you, e.g. take the Iittle one in a pram for a couple of hours while you can rest and relax, and catch up on anything that you want to?
What is that you find difficult when breastfeeding atm? I had my ups and downs breastfeeding and remembered 4 months as tricky age with bub getting distracted so easily, but decided to carry on and now it's really easy at 11 month

Bf does get easier and personally can't be bothered with bottles / sterilising etc but does make it easier for people to babysit. It sounds like you need some support and down time but worth checking with GP just incase.

My baby is turning 4 month soon and I too have been wondering recently if I have PND as having harsh feelings towards partner and myself. It’s hard to tell if it’s PND or sleep deprivation as my baby is once again waking every couple hours (also Breast Feeding)
I was going to ask my HV when they next come if they have advice (due a visit from them soon) or wait until sleep improves to see how I feel.

I assume GP would give you anti depressants but not sure. I was on them once and they made me very tired hence why I’m delaying going to see them.

hope things improve, especially work wise, for you.

@Dahlia5 Thank you for your comment. I guess with the breastfeeding it's hard because she is sooo gassy and I only feed her lying down so there's a lot of stopping and starting again.

@Bellatrix13 yeah I was thinking all they could do is give me meds or therapy (which ironically have no time for!) I've done some research and you can get support from an organisation called Home start. A volunteer will come to your house for a few hours a week and help with whatever you want. Sounds lovely but there's a long waiting list in my area.
I hope things get easier for you also x
