I need encouragement

Honestly I just want words of encouragement to get myself the strength and confidence needed to get my driver license and find a job. Anything you realized or experienced that helped you would be nice to hear if you think it can help me. I dropped out of HS in junior year and I have trouble talking on the phone so I never call other people and I can't bear to look at any text messages. I've lost all my...well very few friends out of shame. And I dont leave the house unless it's with a family member for an errand and even then I'm constantly scared I'll see someone I don't want to see. And I have trouble asking for help. But I know I just need someone to support me and I could do it I just dont have anyone. For now I've started working out in the garage to hopefully help with my low self-esteem but I know that will take a while. But I dont want to be hindrance to my family anymore. They're not very reliable or communicative but they're still letting me live with them but I want to make progress towards being independent. So please any encouraging words or experiences would be nice to hear. I want a job and driver's license.
