Disclaimer: I'm listing my symptoms to find other who may relate. While mentioning possible illnesses is good and all, I am not looking to get diagnosed by the internet. I am in therapy and considering seeing a psychiatrist.

General: I typically experience my sadness in waves that almost follow a schedule, very rarely does stress trigger anything. When a episode is over, I am not hyper by any means but more so just normal. Normal as in how I was before having episodes.

Episode Symptoms:
Lethargy, zero drive, heavy heart, tiredness, inability to focus, inability to socialize, disconnect, day dreaming, and headaches.

Issues: While I constantly don't feel this way, it's dehabilitaty when I do. I can't cry anymore, I can't feel love or care from other people almost as if it's fake, I can't sink love into new people, and I constantly feel like a burden or dumb in school.
