For does who believe their stuttering is severe…how do U cope?

For does who believe their stuttering is severe…how do U cope? I’m worried about my future and living life because I’m ashamed of stutter and recently it has gotten worst I believe I’m worried about eventually getting a job and just living my life. How can I function if I have this severe stutter? (I can never get out my words and I always have to switch my words for something else cause I can’t say that specific word). Plus I’m ashamed of it. How am I going to find friends and communicate with others
