Advice to overcome blocking?

Advice to overcome blocking? hey everyone, i've been stuttering for quite a few years now and have always seemed to have a problem with blocking. the only ways i can get some words out is by swearing, apologizing or going "bleh". pausing to take a deep breath sometimes works but not always and can come across as annoyance at the other person in the conversation. all of these are incredibly embarrassing and inappropriate in more important or formal situations so i was wondering if anyone on here has their own methods they would be willing to share
