Why do I feel this way

I feel totally useless but it's not because I don't have anyone to call mine but cause I feel stupid. And everyone else seems so much more accomplished and seem to know where they are, where they are going.
When I imagine myself in a relationship, I feel that I would get bored of just one person or is it just an explanation I give to myself for having no deep personal relationship with anyone yet or is it completely false and I'm yearning for love.
I'm more in my head than I am in this world.

I think you just have to be glad that you have yourself. Ive felt this way sometimes even tho i myself have a partner (thats sorta weird but bahaha dksnslsb :) maybe you could try and make friends online, like on this website :) i would gladly be your friend. if youd like. if you dont its ok :). unMMm i just hope you feel more useful and positive ❤️‍🩹

mr. Machine,
Sometimes its not about finding the right one, its about being the right one.

Would you like to chat? I'm pretty bored

You can't base your worth on being in a relationship. That will happen for you in time. Oh, by the way, some of those people with their special someone are entirely miserable, trust me.
