有些東西令我覺得....
一些is some
一些東西 is something
令我 makes me
覺得 feel
usually we will have 覺得 omitted and :
一些東西令我高興
something makes me happy
however, if you want to make the sentence complete, something should be changed to there exists(there is) something:
there is something in chinese is 有些
有些東西令我高興 is a common pattern
