Hi Malek, you are trying to use a comparative adjective to describe ‘things’ and this is perfectly OK. You don’t have to compare one thing with another (although it is implied in your sentence – things are getting worse than things were before). The problem is you have picked an irregular comparative. In most cases, the comparative is formed by adding -er (hard, harder -- cold, colder -- big, bigger) but a number of common adjectives are irregular, forming the comparative with different words: good, better -- bad, WORSE. There are other rules, such as ‘words of more than two syllables form the comparative with ‘more’: beautiful -- more beautiful’. When in doubt, any good dictionary should show you the correct adjectival word ending.

To say things are (being) worse is to say things are getting worse. If you really want to emphasize the badness of it, you can also say that things are getting worse and worse (=things are getting ever so worse).

not quite: things are getting worse
