Spaceboy2xx1's journey

I'm entering the workforce for the first time and could really use some advice and encouragement. I've been through a few work programs, but they didn't lead to employment, just some experience for my resume. I'm focusing on retail and cleaning jobs and have crafted a functional resume that highlights my skills in a positive way. I have nice clothes and take care of my appearance, and my therapist has told me I interview well, which gives me some confidence. I understand that interviewing is just about having a conversation. I've been advised to apply directly on company websites instead of using job boards like Indeed, and I've done quite a bit of research on the hiring process. However, I still feel overwhelmed by the complexity of it all. I'm looking for guidance on a few things: 1. How do I effectively find and secure a job? 2. How can I manage the anxiety and fear that comes with starting work and learning new things? 3. What are some key insights or tips that new workers should know? 4. How do I cope with workplace politics, drama, and feelings of injustice or favoritism, especially since I left my last volunteer position due to these issues? Any advice would be greatly appreciated.
