Let's see, from 45 to 48-50 in quant is from 68th percentile to 78th-90th percentile. On verbal, 31-33 is 59th to 67th and 35 is 74th.
Those are decently ambitious targets for 2.5 weeks. Most people would need more time. Do you have any flexibility with your test date?
You mention time management and you *might* be able to make some progress on that in 2.5 weeks. You probably won't fix it completely (that usually takes 4 to 6 weeks for most people), but if you can make some progress, that might help you pick up another couple of points on quant.
Read these two and start doing what they say:

For verbal, each question is worth the same - RC is not worth more than SC. It is the case, however, that getting a string of questions wrong in a row can be very harmful to your score, so that might be why you're seeing issues when you struggle with RC (because, of course, then you might get 3-4+ wrong in a row).
What do you think are the common factors when you do NOT perform well on RC? Are you having to race to read and answer, so you don't spend enough time on any one question? Are you struggling to comprehend the topic / passage? Are there certain topics that give you more trouble (eg, science / technical)?
Re: the early anxiety, why do you think you actually get them wrong? I assume that you're making careless mistakes - you do know how to do the problem after, but you make a mistake in the moment from nerves. Are you rushing a bit on these because of the anxiety, and not double-checking your work? What kinds of careless mistakes do you tend to make? (eg, math / calculation errors, solving for the wrong thing, not reading all of the answer choices carefully and/or picking something too quickly, etc)
Go back and try to figure out HOW the errors actually manifest. Then we can come up with habits that will help to minimize them. (eg, if you solve for the wrong thing, you'll double check your work on the early problems. If you rush through the verbal answers, you'll make yourself mark down a symbol for each answer that indicates that you actually did read it / pay attention to it. And so on.)
