Hi

I am 20 and paranoid and live with my parents too. Has your transition to the US been hard? Do you still have old friends you can talk to? I think that such a huge move to a new country (especially one on the opposite side of the world) takes so much bravery!
I don't know anyone else who feels this same way about paranoia and anxiety, especially not anyone my own age. You're the first person who I've heard of being in a similar situation mentally.
I am bad at coping with my anxiety too, but I like things that help me feel brave. For me, I love things that feel adventurous, when I can overcome anxiety to feel adventurous. Like if you can remember anything that used to spark a little flame in your spirit. Maybe from books that are fantasy or adventure (like The Lord of the Rings), or from music that stirs up feelings of freedom and emotion. Or I will write quotes on my hand that remind me to feel alive. Like "dont hesitate or allow yourself to make excuses. just set out & do it. you will be very, very glad that you did. -christopher mccandles"
and music that makes me feel better is "I love you, honeybear" by father john misty.
i think i have a lot of coping methods (i carry essential oil blends, and self care kits and i know to exercise and hold my dog and drink water and get out of my own head) but it's hard for me to actually do these coping methods when i need to, because i get stuck in very sad ruts and just lay down and don't move.
Maybe you could get a therapy dog?

(If you like dogs!)
