It sounds like you're going through a really heavy time, with low mood and low self-esteem. Just so you know, "mind reading" isn't a disorder. It's something many of us do, where we feel sure we know what others are thinking about us, and it's usually negative. Say a friend takes a while to reply, and your mind jumps to "they find me boring." Most of the time they were just busy, but the thought feels so real that it chips away at your confidence. The good news is these patterns can change with the right support.
Next Steps
Please consider booking a consultation with a counselling psychologist or psychiatrist, so someone can understand what you're going through properly. Therapy like CBT works well for exactly these thought patterns. Until then, when you catch yourself thinking "they must think badly of me," try pausing and asking, "Do I actually have proof of this? What else could be true?"
Health Tips
Be gentle with yourself. Try to keep small routines going, like regular sleep, a short walk, and meals on time. Talk to someone you trust about how you're feeling. If things ever start to feel hopeless or you have thoughts of hurting yourself, please reach out to a doctor or a helpline right away.
