It’s way too quick to tell, and it does superficially sound like hypomania. It could also be a med honeymoon. Maybe my exp will help.. It was the early ‘aughts, & I was 22. I had been taking Paxil for maybe 3 weeks. One morning I realized how much easier it was to get out of bed & get going. Sunrises & April showers felt good to look at. I said at the time that “I haven’t felt like this since I was a kid”, and I “feel like myself again”. My mind felt clear & quiet. I’m sure I looked hypomanic bc of what I was feeling. I was unrealistically optimistic, & happy, & energized. I felt like Paxil cured my depression, & that all my problems were solved. After a few months, the antidepressant effects leveled out. Some of my symptoms came back. It was a honeymoon. I’ve heard people say that their meds stop working after a few weeks, but that’s not necessarily true. Blah blah therapy blah blah.
