Struggling with ADHD and Agoraphobia

I suspect that I have Adhd and that I'm agoraphobic, I struggle to find a therapist but have recently found one I'm afraid I won't have the guts to tell them everything out of fear that I'll be told I'm full of sh*t, I struggle to focus on what people are saying in conversation and get to anxious to ask them to repeat what they say. I have to reread the same sentence because I can't focus while reading too, I have bad memory, and get lost in my daydreams 24/7. I'm afraid to go outside because I feel like everyone around me talks badly about me, I care too much of what they think of me, I'm also afraid of running into my middle school bullies or anyone I use to know either from school or old jobs, even if we left off on good terms, I don't want them to see how miserable I look. I prefer wearing a face mask in hopes of not getting recognised, but it doesn't help much, I do get random panic attacks from time to time, but they're not often.
