Help please

Idk if I have anxiety and depression but sometimes I think I do.I feel empty a lot and worthless and tht I’m never good enough. and I always second guess myself and overthink a lot of things. I also have trouble letting people in. recently sometimes I think I have panic attacks and my chest feels like someone is stepping on me. I want to see a therapist but I’m scared to ask my parents but I feel like I’m going to break soon.
