Eighteen, lost, and learning

Hello everyone!! I recently turned 18 in November. I struggle with my mental health due to unfortunate choices my cousin made towards me. My parents have babied me for years, and I barely know how to cook or survive on my own. Im not even sure how to get over my extreme paranoia and anxiety. I feel hopeless, like ill never find a partner or have a shot at any of the dreams im working towards. If anyone has any helpful yet a little beginner recipes, advice, how-to-dos or anything that may help me finally start trying to learn how to 'adult' on my own, please. Id love to hear it!! Thank you so much.
