Schizophrenia? I hope you can help me,

Hi, my mom suffers through schizophrenia. I was wondering if it's inherited or not. & if I could genetically get it. I have anxiety (my doctor said as well) I do not go to therapy or counselling. My hands continuously shake (they shake more when I'm scared or nervous) my legs do as well but they shake rarely when I'm really nervous or scared. I often end up crying really fast. I over stress too. & lately before I sleep I'm experiencing hallucinations & I see images around me when my eyes are closed & even open. & they're all bad imagines that scare me. Something I've been experiencing for years now is underneath my left breast I get a sharp pain that really hurts. I have to press on there & not breathe for at least 30 seconds for it to go away. I receive this pain at random times & the pain gets sharper if I inhale deeper. I'm just wondering if something's wrong. I don't feel like telling my parents or a doctor, so I decided to try this. I hope you can help me, thanks for taking time.
