i literally can’t go anywhere or do anything

i need help dealing with this. it’s terrifying going places. like i literally need someone to hold my hand in order to go anywhere and the thought of doing it makes me wanna cry and feel like i can’t breathe. it’s not just leaving my house but with literally everything. everything seems to make anxious to the point i feel like im paralyzed. please help. i feel like im being ridiculous bc logically theres nothing that happen but i have this horrible constant fear and panic even when i try to reason with myself
