It can be done...though it's hellish at times. I just finished up my degree and even have a half-decent GPA. My biggest issues were focus problems, hypevigilance and sometimes getitng triggered by course material. Luckily the uni helped out and the profs were very understanding. One thing I'd say is...if possible, try to get ptsd under control as much as you can...bu tthen, at times (on those rare occasions when I could focus well), I found school to be a good escape...so it kept me sane even as it drove me nuts. But...if you're thinking of doing grad school...might be best to wait with the undergrad until you can control ptsd better...otherwise it could mess you up (gpa-wise etc) for grad school...Just something to think about. Good luck.
