Anyway to stop stuttering?

Anyway to stop stuttering? I am 23 male and i stutter a lot. It doesn't matter i speak my native or 2nd language i stutter in both the language. Friends mock me, i mean they are not making fun or bullying but when they say they can't understand me because i speak too fast when we are in a group, it feels bad, i loose hope. It feels like I can't have a strong presence anywhere even at work. I don't know when i stutter it feels like something happens in my mouth which doesn't let me speak clearly. My words are unclear or sometimes i speak too fast, even i can't hear them in the recording. I can't afford any therapist. What should i do? And also it has grown so much in the last couple of years.
