Undergraduate / UC Personal Statement: Single Mother [2]

I am in the brainstorming phase of writing my personal statement and need advice on how to structure my essay. Here are some bullet points on what I would like to talk about and share.

1. Being a single-mother to a 18-month old boy
2. Being a recovering alcoholic and addict at age 25 (28 now)
3. Traveling for 10 years after high school and just starting school now (I have issues/insecurities talking about this because it wasn't like I was traveling/having a blast the whole time-- my addictions were worsening everyday)

Would that be an overshare? Thanks in advance for your comments
