Trauma affected my grades while in undergrad, how will it affect me getting into graduate school?
I'm going to make this an answer rather than a comment; I hope others will react to it, especially if I'm wrong.  (I'm a teacher, not an admissions officer.)

From what I understand, you had good grades at the start of your college career.  Your grades declined for external reasons.  Your life is back under control and your grades are back up.  You have a little more than a year to gather good grades on your transcript.

Go for it.  Apply to the schools you'd like to attend, but apply to a couple of Plan B schools as well.

Here's the part that may be controversial:  You might want to include in your cover letter something like "You may notice that there was a slump in my grades during my time as an undergraduate.  That was due to a difficult personal situation, now resolved."  (Thanks, Nate Eldridge, for the fine phrase.)

The other choice would be to mention the grade slump not at all.  In any case, don't make a big deal of it.
