What would you do?

My friend and I are both in our mid twenties, we’ve been friends for roughly 5-6 years. Everything was fine when we met but as the years have gone by she seems to have regressed mentally and by that I mean the older she gets, the more she acts like a 10 year old little girl.

She gets excited by kids toys, talks about how she names inanimate objects and gives them backstories and is very overly sensitive about everything.

Now she does have some past trauma which is probably causing all of this but she won’t get help for it and thinks that acting this way is normal!

I don’t know how to talk to her about it without her getting upset or thinking that I’m criticizing her or that I hate her.

Unfortunately, I’ve grown tired of it all and I feel as though she’s holding me back, not to mention the negativity 24/7. I want to grow into my adulthood with people who I can relate to, not someone who expects me to keep a conversation about a kids program that they watched last night.

I know I’ll probably get judged for this post and people will see me as being a bad friend for wanting to ditch her but you can only take so much of this before questioning your life choices.

So what do I do? Stay friends with her and deal with it? Or cut ties?
