extreme stutter and don't know what to do about it

extreme stutter and don't know what to do about it So I've been stuttering all of my life but it hasn't been that bad. But in the past couple of months (probably due to high amounts of stress in my life) my stuttering has worsened so much that it's hard to even have normal conversations with my family and it's extremely frustrating and exhausting. I can't get more than a word or two out without freezing and repeating it. It takes me like 20 seconds to say a single sentence. I'm an intelligent person and I'm only 18, but this just makes me so sad. I can't get my point across or even share things with people because of the stutter. I don't even want to talk anymore. Does anyone know how I can manage this? I can't live like this
