Simply put, I was texting a girl from school last year for a few days but then she eventually asked me to leave her alone. I didn't even text back "okay" or ask her why however I cannot stop thinking about her and haven't been able to for 6 months. Furthermore, I have been unable to leave the house without thinking that I saw her walking since June. I have even thought someone was her who didn't look at all like her. I am constantly daydreaming about talking to her 24/7. I am not romantically interested in her I am just very lonely. I have gave myself panic attacks and delusional thoughts about why she asked me to leave her alone. I know I am being ridiculous but I am in a lot of pain. What should I do?
