Any advice on getting through blocks and bad habits?

Any advice on getting through blocks and bad habits? Been stuttering ever since I was able to speak words but I used to stutter “normally” until a few years ago and now I have this nasty habit of closing my eyes every-time I have a block so it just looks like I’m shitting myself lol. But just wanted to know what are some of yall techniques to get thru this. I went to speech therapy once as a child and I still remember some of the stuff they teach you there but it’s been a minute lol.
