Adult SH

I’m over 20, and I didn’t start sh until I was fairly old (maybe around 18). Sometimes I feel really invalid or dumb for not struggling with this since I was young/not struggling for years (it’s only been a couple) I also feel really embarrassed that I’m an adult who still struggles with sh. I know it can affect anyone, and I know it’s not related to age, but I can’t help but feel a bit ashamed. I started later in life compared to some people and I feel a bit dumb, like surely I should’ve known better. I just wanted to rant, and see if anyone else feels the same or can relate. I know plenty of adults do it, and I know plenty of people start later, but I guess I don’t see it talked about as much.
