Is this what a hypomania feels like? Could a reaction like this indicate i'm bipolar?

So Saturday (march 19th I think?) I took my first dose of zoloft at 50 milligrams for GAD, i've had panic attacks since I was like 6 but learned to deal with them, but the constant anxiety never fully went away, and would often get worse in winter/spring

Like 5 or 6 hours after I took my first pill I woke up at 3 am, had roughly 3 hours of sleep, and felt extremely energized. I knew from the second I woke up I was not gonna be able to fall asleep, I still tried for 2 hours, because I didn't wanna mess up my schedule, before giving up at 5 am and doing a school project. As soon as I got out of bed movement just felt so good. I felt so fast and strong and lightweight despite being on so little sleep. I felt soooooo motivated and happy. 

Started doing a school project at 5 am even though i've been procrastinating on it the whole week. Never felt so smart in my life, its like I didn't even have to think, the ideas just appeared in my brain. I would start writing a sentence and before I could finish I already had 5 more for different areas of the project, so I would constantly jump around different sections of the project just because I knew I had to write the thought down. Had to even stop myself from doing that because I could barely finish writing a sentence.
I've been feeling like this since then, and I actually WANT to do work, like I have a strong urge to be productive.

I also just felt really confident, I feel like everyone loves me, i'm the life of the party, i'm the funniest person ever, and I started talking to people more.

Its also really hard to sleep, I take hydroxyzine to help me fall asleep and I still only get 4-5 hours a night. Despite that I feel like I have wayyyy more energy than when I was getting 8 or more hours. This energy also lasts the whole day and I only feel tired a few hours after taking hydroxyzine and zoloft (taken before bed) 

My appetite has been decreasing the past few days and I wanted to skip dinner a few times, but its also not hard to force myself to eat so I don't starve. Like I have no interest in eating but I know I have to so I have no problem doing it.

I've also just been angrier the last 2-3 days, before that I was super happy pretty much 24/7 since taking the pill. I get mad at pretty much everything and today its been honestly hard to be happy? I only feel a tiny bit happy when theres a reason to, i'm mostly just angry or don't care is this normal?

Sorry for writing so much cause the last 2 weeks have been wild, can yall help me out and tell me if this is normal on zoloft or this sounds like hypomania/mania and could I be bipolar if so?
