Social anxiety as a first time mum

[newmum10000000]

Hi all just posting to see if anyone else feels the same, I’m only 24 and before giving birth I was actually so social, always with friends and going out etc. since having my baby girl who is 6 months now I literally see my friends very rarely as they are all party animals and still have that uni student vibe whereas I am always with my little girl, doing baby things and she is honestly my best friend I hate being away from her and hardly have been since she was born! I’m seeing one of my close friends tonight for drinks whilst my mum looks after my baby and honestly I am just so so anxious about it. I keep freaking out and wanting to cancel. But also I know I have been looking forward for a night to see a friend in so so long. I know my baby is going to be fine as she knows my mum well and I’ll literally only be gone for a few hours, have pumped milk for her and I also won’t drink a lot so I won’t be drunk when I get back. But honestly I just feel sick with dread. Im feeding my little girl now and just keep looking at her feeling bad about leaving for a few hours tonight! Also just feel anxious in general feel like I’ve forgotten how to socialise So crazy when before I was always out and about doing things, any other mamas the same and how to not feel guilty or anxious to have some time away from baby?

It's really normal to feel the way you're describing and mum guilt is very real.
But you will have a lovely night seeing your friend! And you have nothing to feel guilty about at all. Your daughter will be safe, warm, fed and adored. You're making sure she is with someone who will see to that and you're coming back home later on.
You're still pretty young so it's understandable a number of your friends will be in the uni stage of life at the moment, but that won't be forever.
I'd just be careful of referring to and thinking of your baby as your best friend. She's your child, you're her mum. You can be close and really bonded but she's not your bestie. That's a lot to put on her as she grows up otherwise.
Enjoy your night and look forward to baby cuddles when you get back. It is not easy leaving them when they're little but she really will be ok.

Agree with @Inkypot .
You need to have some time away from baby to refresh and recharge and give yourself a proper break at times. Plus it's your mum looking after your daughter so you literally need not worry.
Again your baby is your baby, not your best friend. Don't confuse parenting with being a beast friend. Two different roles.
