You could be. But you won't be. Getting denial of serviced on the web running a personal site is like getting attacked by terrorism. Sure, it happens, but it only ever directly effects the lives of less than half of a percent of people even with the most generous definitions of "terrorism". It's the reactions to it that cause damage.

And it's the same reactions to it on the internet that hurt and not the DoSes. Just run your website. If it gets DoS'd no big deal. It's not like you even need a single nine of uptime consistency.

I've run my for 20 years from my home connection, I've been a jerk on IRC, I've used it for gaming clans, I've hosted and continue to host tor onion services. I have never been DoS'd.
