I second Omega's suggestion for therapy. Specifically group therapy, give it a shot. Not necessarily because it'll "cure" you but it'll give you a place to safely express your feelings out loud and not feel so alone. These forums are good for that too actually! Another few serious suggestions for managing depression:

- Checklists. I normally need to WRITE OUT what I need to do for the day, and on my bad days those checklists look like 1. get up 2. shower 3. eat. It helps to hold me accountable and motivate me a little, and reminds me that even if the tasks are small I still GET STUFF DONE.

- Protein and Iron. These things can help with energy, either in food or supplement form. My go-to depressive episode food is trail mix. No effort to make and shove in my mouth, tasty, and it gives my body a little extra boost.

- WRITING WRITING WRITING. Write how you feel during a depressive episode. It helps to validate those feelings later and purge them while they're happening.

- rubber bands for self injury thoughts, if you get those.

That's all I can think of right now ahhh. PM me if you ever wanna talk about it.
