Hang on in there buddy, I've been where you are now.
I've got experience with exactly the feelings you're dealing with, the apathy, hopelessness and the desire to start something and finding no one with the enthusiasm required to go on. Also, I'm located in Berlin.
What helped me the most at the time was talking to and really connecting with people who were in my shoes at some point in their lives.
I've just created an empty Discord chat, if you want you can use a throwaway account and find me there https://discord.gg/4zm7TT
I'm sure there should be many, many more.
