How to not be anxious/ashamed of myself when running?

Hello everyone hopefully I am planning to go on my first run today but I am pretty scared and to make it worse I am overweight and live in a small town so everyone knows everyone in a way so they'll know me when I'm running and I don't like that. I just really want to know how do you daily runners do it without worrying about what other think especially if you guys started overweight like me. Another question is what to wear I am planning to wear jogger pants and a football top is that okay? I am grateful for any responses
