Daughter is driving me crazy

My daughter is 8 months and lately nothing makes her happy. If I put her in her bouncer she starts complaining(not crying) and keeps making a “mmmmmm” noise with a mean face or starts screaming. It’s the same if I put her on her tummy to play with her toys. She’s like this over everything. The only thing she is content with is watching “trolls” or “Moana”. And I’m trying not to let her watch tv unless I’m absolutely trying to do something like get ready for a drs appointment. She just got over separation anxiety from me a week ago where I had to be holding her 24/7 or she would cry her eyes out. Any advice on how to keep her happy besides tv? She also has a tooth that just broke through a few days ago.
