Dealing with embarrassment and insecurities

so this is my first time posting on here so my apologies if by any chance I make any type of mistake typing or if this type of post inst accepted. I was wondering if other autistic people have a hard time dealing with embarrassment, like dwelling on it or constantly remembering something embarrassing and then getting scared or anxious. I have a really hard time handling embarrassing situations and it's made my self confidence drain severely, so my point is I am wondering if other autistic people deal with this too and if so what advice can be given. I am very recently diagnosed so this is all very new to me.
