My stutter is controlling my life mentally Hi everyone i just really need advice because for years my stuttering has kept me in a negative and angry mindset for years and i need it to stop because of a few reasons 1. My relationships always fail because im so negative and my current one is on the rocks 2. Im sick of living in fear i just wanna feel no shame so i can live and feel my best self 3. The dark thoughts come back often and it scares me. Dont get me wrong i hsve a great life just my stuttering really holds me back i have a good job, good family, have friends etc any advice?
