I have been suffering from stuttering as a child and still as a adult

I have been suffering from stuttering as a child and still as a adult Now my stuttering has worsen as sometimes when I speak to any stranger I feel like someone trying to choke me or there is something between my throat. This type of stuttering has cause me a lot of problem as I cant speak to anyone and it makes me very nervous and anxious about myself. If anyone can help me I would really appreciate.
