First time backpacker/I want out?

Hello! I made an account specifically to ask this question lol. I want to start backpacking because I'm so sick of being where I am currently, theres nothing to do or see! I want to go west maybe and just see everything the sunsets, the people, the ocean, and basically things I've never seen before. I know it sounds ambitious, but ik I need this. I'm 20 and I've literally been sheltered and in my house my whole life!! If ANYBODY has tips for safety, money, equipment, experience, warnings, people or groups that don't cost one trillion dollars are wanting the same please help me out and let me know! Enlighten mee
