Hey,

I'm not diagnosed with Bipolar, but I've had this feeling of possible mania for about 2 days. I have a feeling of great energy, feeling really active yet slightly more irritable to sounds which also annoy me when I don't feel this way. It makes me feel concerned.

For up to a year, I decided to fight depression in better ways, such as exercising, attempting to create and focus on hobbies (it's hard, but I'm gradually trying). I'm working on moving on with my life and heading a road that is right for me.
I work on my mind allot, right now with Sudoku puzzles to increase my focus.
I continue to fight, to earn a voice of my own, since I have allot of thoughts stored inside and I want to talk them out one day.
I have this feeling that my feelings can seem manic because I'm "bursting" a shell of isolation and entering the outer world, probably in such a huge blast that I feel manic?
I feel like I'm coming closer to know what is my road, and it makes me feel filled with energy. I don't know whether it's happiness or mania.

I should note that from my consciousness, I have always had some sharp mood swings, such as feeling bad during the morning, but after lots of brooding, thinking or exploring knowledge about things that bother me for instance, I am filled with hopeful energy towards life.
And I've always been dealing with many thoughts about the world, and about how it can really be a better place. I think my ideas thoroughly, but now they're boiling, and they want to be heard.

I am really confused. I am currently sitting in my room in front of internet tabs, The Sims 4 (video game) and Ableton (music producing program), the usual. I am always at home (except for the gym and if meeting with friends). I have thought about working but minimum-waged full-time is not worth it for me, and I now have the responsibility to prepare for an admission test for university, which is 1.5 months ahead of now.

I was wondering if what I'm experiencing has a reason?
I can find no source which says that a manic episode can be normal, it all links to Bipolar disorder. Though I'm not even sure if I'm even experiencing mania, so this is why I'm asking here.

Well mania would, by definition, cause problems for you. If it doesn't have negative impact, it wouldn't be a pathology. Diagnosing involves considering symptoms and determining how many would apply toward a dx and the level of negative impact they have on one's life and functioning.

You describe a feeling of having an increasing sense of what you want and gaining energy from it. That's cool and would be naturally exciting. Maybe it's mania, but maybe it's just feeling driven by feeling a sense of purpose. That WOULD be exciting, especially having come out of a fight with depression.

It really would be something a professional would be needed to sort through. I know you know we can't diagnose and are just asking for opinions, but I have to say it's particularly obscured by normally energizing factors. And no mention of a pattern repeating over time in larger swaths of time. Or causing problems.

So, sorry to give a pretty predictable answer, but this seems particularly hard situation to even guess. If it worries you (or those around you are expressing concern), by all means, seek professional consultation.
