Never discredit your gut instinct. You’re not being paranoid. Your body can pick up vibrations, some better than others, and if something deep inside you says something’s not right about a person or situation, trust it and keep it pushing.
You said you wish you knew what yo purpose was... Answer = what do you want people to remember you for when you die? What you wish someone would've did for you as a child & even right now? What are your morals & values? What can give you a peace of mind no matter how much bs you going through? What examples you want to set for your future kids? What you give a person everything no one gave you? etc. The answer to all them questions will lead you to yo purpose... Stay Blessed
