I genuinely hate myself sometimes
We should work on that. What do you think would make you like yourself more?
I am not sure. I feel like nobody else likes me and that I'm useless.
I like you! You are a unique person and it is important that you accept yourself just as you are.
I am too different and complex to be liked by you.
Try to be more positive about yourself. Being complex is way better than being boring and simple. Really start working on accepting yourself more and you'll be happier in life.
