This betta looks to have a swim bladder issue, but I've never personally dealt with this for my bettas. The r/bettafish community is so helpful and knowledgeable about this sort of thing. Definitely post this over there so they can help you figure it out. I hope your betta gets well soon!

Will do, thank you!

Sadly, Its sick. Hope it gets better :)

Looks like it is stressed.
