Is it my fault i can’t speak to anyone about my problems?

I haven’t had a conversation about mental health or my wellbeing to anyone in my family and it’s getting really tiring bottling it all up, but every time i think about talking to them i get filled with a sense of dread and i think it would only make it worse. I feel like an outcast in my own home and it makes me miserable. Is anyone else reading this going through something similar? I’d love to talk about it with someone.
