I am really curious what makes people live. Do you live because you live? or Do you have something you eager to?
sometimes I ask the same from myself. Yes, there are things and people whom I live for. I am tired after work. But I don't want to give up.
I can advise u (though I am not the one very good in anything) don't give away what u like. try to think about them. Sometimes I also look at the sky and think : "I don't know whether they shine for me but I like them as they r indeed^ so cold, do high, so shining" I like them and I don't care if they let me do it or not.
I think what helps the most is hopes and goals for the future. When there's no motivation at all, they can be super small and basic. For example: getting into a new hobby and buying tools for that hobby from Amazon. Waiting for the package to arrive. Or: a sequel to a show you like coming out in 2020. Now you have to wait for it! And stuff like that. Finding hobbies that you really like and mini-goals that motivate you.
