It’s definitely not all in your head.
Please practice listening to, and believing, what your body is telling you - I too have had to get so much better at this, but I am really happy it’s paying off.
I listen to my body about diet, sleep, rest away from the kids (super important!!!!), in a way that I just didn’t have to when I was younger - I muddled along fine, had a few glasses of wine, things sorted themselves out! That definitely doesn’t happen for me anymore.
Nobody knows you, or cares about you, more than you do - be an ally for yourself.
Listen to yourself like you’d listen to a dear friend that was telling you how they feel…
You will be a million times better parent if you look after your own needs on a level priority with everyone else’s
Go and see a specialist and prioritise this now xx
