"social skills" and "dating life" are more than one thing, so "was" should be "were".

On rough days, and
in rough weeks/months/years. You could use "during rough days or weeks".

Some people allege that you should not start a sentence with a conjunction such as 'and. However, this is a stylistic preference rather than a grammatical ‘rule’. If your teachers or your organization are inflexible about this issue, then you should respect their opinion, but ultimately, it’s just a point of view and you’re not being ungrammatical. If you want to defend your position, you can say that it’s particularly useful to start a sentence with these conjunctions if you’re aiming to create a dramatic or forceful effect.
