How can I stop stuttering entirely only by self-help?

How can I stop stuttering entirely only by self-help? Everybody online suggests me- consult your therapist. Here in India when people are dying of hunger we don't have friggin therapists here. So tell me how can I stop stuttering or at least improve my enunciation. Here are a few things about me: *Sometimes I don't stutter but sometimes I do. I think it is triggered mostly by anxiety. *I have started stuttering a lot these days maybe because I have a lot of stress these days. *I have a habit of shallow breathing. What do you guys think while talking to others (what is the mindset)? Are there some breathing or tongue exercises? Any help would be appreciable.
