I don't know what to do. I feel so lost, nothing seems important, my life seems utterly pointless. Maybe I'm having an existential crisis?

Medication has gotten me this far (functioning in my daily life), but it won't help in answering the questions in my life: why am I here? will I ever be happy? what should I do with my life? what will give me a sense of purpose?

My physical symptoms of depression are under control, but the non-physical symptoms still haunt me. I'm starting to think (passively) about suicide again, because I feel hopeless and overwhelmed. I'm desperate for answers but don't know where to look.

Any advice ???
