I want to manipulate people so I can feel something
Why manipulate people who you care about?
My life is so boring so I want to feel something
Manipulation is not the answer. It is wrong, especially if they are going to get hurt in the end.
Well I don't know what to do then can you help?
If you want I can suggest seeing a therapist. I think giving it a chance could help you identify some issues you might have and be really useful to see things from a different perspective.
