I notice I been stuttering since last year is their anything that I can do to stop it?

When I talk to people sometimes nothing won't come out or I'd feel like I'm out of breathe or get my words messed and confuse others n they look at me funny.I feel like this is affecting my life and now everytime I talk I'll stutter or just nod my head n don't say anything at all when someone Is speaking to me.Im also afraid that this will be a problem for me in the future like when I'm being interviewed for a job..is their anything I can do to stop this stuttering?
