I've already taken it four times. Twice five years ago so I waited and took it again twice this year. I studied for an entire year, went through all of the books, literally no progress. My scores are stuck at 154 verbal, 154/161 math and 5 writing. And my GPA is 3.62/4.0/4.0/3.9 (I took courses from four institutions to graduate early.

Hellloooo welcome to the fam! 
Generally, schools won't send official rejections until they've gotten their incoming class put together, so around April. Some schools will send rejections to their hard no's and not send anything to their maybes just in case. There's really no way to know. I know of a few schools that do interviews in early March, so their interview invites might still be floating around, but for the most part, they will have been sent out by now. 
Don't be discouraged! For almost all applicants, the first round does not work out (myself included). 12 is a pretty typical number of schools to apply to, honestly, and some people will recommend at least 15. You probably are a great applicant, but the problem is that you're up against thousands of other great applicants for a really limited number of spots. Think 1-5% acceptance rates at most major universities for Clinical Psych. 
Overall, it seems likely that most invites are out, but there can be an occasional person who gets invited after interviews or gets pulled off the maybe list. It's hard to say because each school is so different. It's a real frustrating process.
