Hair!!

Hey ladies! I need some help! I'm thinking about cutting my hair in the next few days....I have long hair now and was contemplating on whether to cut it short or just trim it. I need some help deciding & also can anyone tell me if it'll be the worst decision ever? I don't want to cut it and miss my long hair I've always had :( on the left is my hair now, the right are some ideas! I'll take any advice/feedback!
