Unapproachable - lacking confidence - introvert

[Countrylifemama]

I wouldn't say I've got a big group of friends and i guess older i have got the harder i find to have social chat and speaking with people.. not sure why or what happened as i wasn't ever like this. anyways there's a group of school mums i go out with some of them im closer to i would say as we chat/playdates etc but i find myself in the wider group when we are out really socially awkward... one of them also said i look unapproachable esp in the school run in mornings :(

i tend to overanalyse and over think but this is causing me even more anxiety... i struggle with chat on the whatsgroup etc and feel like im starting to lose confidence and think im the boring one in the group... I just feel awkward…

i just feel at wits end as im generally an introvert and i dont know how to be more 'fun'…

guess looking to hear from others who maybe in the same boat and how they have overcome this?

aibu to speak to them directly about some of the comments? Or how I feel?

I wouldn't approach directly otherwise you risk coming across as aggressive and might push people away.
It's really hard to be in this position, it feels horrible and you almost get caught in a vicious cycle of paranoia about how you're coming across. I'm sorry this is happening to you. Have you considered 'acting the opposite' so instead of perhaps going to your usual withdrawn behaviour, pushing yourself forward in the group? Deliberately starting conversation in the WhatsApp group or when out?
I find people are generally happy to talk about themselves, and asking questions shows that you're interested in them, you listened to things they've said previously, and that you are invested in their well-being. That's how I tend to make conversation in the main.
Along side this if you're feeling really anxious and self conscious you could always access CBT which can help you with social anxiety and low self esteem.
