Does anyone else feel like this? I’ve forgotten how to talk to people!

I feel embarrassed and actually really sad about this but I feel like I’ve lost apart of myself and forgotten how to talk to other adults! I’m a SAHM to a 2 year old. I feel like when I go out to mum clases or places where I would interact with people other than my family or even friends who barely know me, I can’t communicate how I used too. My vocab has gone out the window, i use very basic language and don’t talk how I used too before having my baby. I feel like I get muddled up and the BRAIN FOG - don’t get me started, I had a bad memory before but my god, my memory is awful now!! Someone could tell me something and literally 2 seconds later, I ask the same question’s, fogetting what I already said! Yesterday, I was speaking to someone who was saying she was moving house and I said “oh what a lovely start to the new year” IT’S THE MIDDLE OF APRIL!!! My friends will call me for advice and I get all muddled up and forget how to give out advice, like it doesn’t even make sense and I don’t say the words properly (my background is a counsellor) I feel like I’m giving all the wrong advice! I also feel like I don’t know what’s going on in the wold, the news, too excused and overstimulated to read into things - people have conversations with me about worldly affairs and I change the subject and feel like an idiot because I don’t know what they’re talking about! So because I can’t contribute to the topic, I close it off. I just feel like a mess, embarrassed, I don’t remember anything, I want a job so I can just get back into it he swings of having a “normal” life but I know it’s not realistic right now so what do you guys do to change this? My memory issues is the thing that’s bothering me the most..I feel like I need help 😓😓😓
