I really don't know if I have a b mental disorder I need an answer I'm overthinking and I'm calm and

Scared)
Am genuinely so cunfused if I had a manic episode for 2 years(I'm pretty sure I don't have bipolar or BPD since I was never diagnosed) from late 2021-to early 2024 bcz I was really reckless I never needed that much sleep I was chaotic messy emotional I always felt as if I was sick and everything felt hot I felt sick but I wasn't I suddenly started crying a lot when I was never like that I was feeling rushes of emotions at once I was so jumpy sleeping for 1-3 hours then waking up and doing anything like skincare shower everything It made me feel mentally stable and one day I I was at the graduation area and I acidentally told my friends to not hug me to much because I was sweaty then I realized that sounded so mean then I started feeling depressed like really quickly the moment I sat down waves of sadness tiredness exhaustion overstimulation started hitting me after a whole 1-2 months of severe depression I suddenly woke up one day calm I felt so normal. I didn't know when the waves of happiness whould appear and the feeling of sickness mixed with lots of energy and then a hit of depression then emptyness arising I feel so calm..to calm. I don't know why but I like this..but I miss the times I whould concern people when severe depression whould hit then luagh with me when I felt the happiest and sickest..but I feel calm. Like the type of calmness when you just returned from school then use the train(I've never used a train this is js an example) hang out with your friends at the end of the school day the mixture of yellow and blue pink and orange felt nice it feels nice..really.
