Since you have Fs and Ds, I would definitely address it; however, I'd probably just describe them as personal relationship problems or something of that nature. I wouldn't go into the specifics you described above. If you can, spin it, ie, despite the personal/family/whatever problems of so and so time, I was able to learn from the experience and persevere to do x, y, z and excel my remaining terms, and whatever else you've done since then.
