Almost perfect. But I would make the sentece like : I wanted to go to the park, but now I don't want to go anymore. 公園へ行きたかった，でも今，もう行きたくない． =>公園へ行きたかったが、今はもう行きたくない。 (1 sentence) =>公園へ行きたかった。　でも今はもう行きたくない。 (2 sentences) The dictionary also tells me 最早／もはや. Can I use it here as well? 公園へいきたかった，でも今，最早行きたくない． =>公園へ行きたかったが、今は最早いきたくない。 (1 sentence) =>公園へ行きたかった。　でも今は最早行きたくない。 (2 sentences) When you make it into once sentence, you would need "かったが、"　for expressing "but" And you need to put "は”after "今”。 PS: ”最早” means similar to "もう”; however, it's kind of rare to use "最早" in a daily conversation. We tend to use "もう" instead of "最早". ”最早” could be more used for a kind of official speach or writting japanese(essay or sth).
