Stress Plus Neglect Equal Breakage?

The past few weeks have been stressful for me for many different reasons and I had no time to take care of my hair. I haven't deep conditioned and I've been combing through my dry hair, to 'preserve' a style, which is completely horrible. With no deep conditioning plus extra manipulation, breakage was inevitable.

I am now working to combat the little breakage:
- First I put my hair in a manageable style: two strand twist (these twist are bigger than my previous ones.)
-I then trimmed the ends. I realized that I had a LOT of split ends. I know when I need to trim, but I don't always have the time to do it and then it accumulates and gets worse.
-The next thing that I will do is deep condition. I bought some Aussie 3 Minute miracle and I plan to deep condition with that and some extra virgin olive oil. The next time I deep condition, I'll add an egg for protein.
