I'm an alien boy who got stuck in this world

I'm an alien boy who got stuck in this world When I was 7 or 8 years old, I consumed a lot of Chyawanprash (which is a warm herbal tonic), which caused me constipation and speech difficulties. I started stuttering, and when I changed schools, I became a target for bullying by both teachers and students. I started isolating myself, and even my parents were unhappy with my speech and began getting angry with me. I'm now 22 years old, and although the problem isn't as severe, I still struggle with stuttering, especially with sounds like 'b', 'k', 'ki', 'ka', 'c', 't', and 'p'. What should I do about this? In my school and in past years, there have been incidents that have shattered my trust in the world, in God, in friends, and in parents. I hate myself (though I don't know the exact reason for it). It feels like everyone is just using me like a tissue. I've been alone since childhood, with no friends, no parents, and no one in society by my side. The world constantly reminds me how different I am from others, like an alien. I can't even take a photo of myself, and I never post anything on social media. When I see a picture of myself, I'm surprised that I'm not that person; it's so absurd.
