A warm welcome to our forums. What you're saying really resonates with me. I also feel things really intensely, feel so much sensitivity and empathy, then again I can also get moody very easily, sometimes my actions feel monotonous and emotionless, and I sometimes feel like I struggle to connect with or relate to others.
I'm not quite sure what it means, but I hope it brings you some level of reassurance to know that you're not the only one who experiences this. It may help to have a chat to a counsellor, therapist, GP, or psychologist about what you're feeling, as they may be able to help you understand these behaviours and gain a deeper knowledge of yourself too. I talked to a counsellor about this as well, and it was really helpful in terms of helping me consolidate my own feelings about these behaviours.
Is this something you've noticed recently, or has this been the case for a long period of time?
Looking forward to hearing back from you.
All the best, SB
