It's not that your problems don't exists or people have told you the right thing for you, the exposure therapy advice sounds like bad, but you also can't expect people to be able to provide you with perfect advice for your situation. Some community, kindness, and generally good advice is all most people who don't know you can do. A lot of us deal with depression or other mental health issues. Even someone outside our or other disadvantaged communities dealing with depression can feel like its impossible to have a fulfilling life or be happy. When you have a disability like a stutter it's not uncommon to feel it's a mitigating factor that makes you uniquely unable to find help. A lot of people are really just positive here to try and dispell that notion. The hope being that you can then get personalized help. Also, when you're that alone you're vulnerable either to a cottage industry of snake oil salesmen, or to a bunch of black pill, hate, or weird incels ideologies. The attempted dose of positivity is also done because we don't want to lose someone to scams like that.
