Also assuming I'm anti-fascist, would them coming to power majorly effect my life (before the outbreak of WWII)? What kind of things would I have to be most likely worried about?
I don't think it is possible to provide a general answer.
It would certainly depend on your occupation, your social status, your age, your gender. After WW1 over 55% of Italy's working population was still in the agriculture sector. Most of them lived in rural areas, but there were also industry workers living in rural areas.
Living in the countryside of a large city was much different from living in a small town - especially in terms of political involvment.
You may still have been illiterate, which would certainly not help in knowing what you were worried about, as perhaps the only direct source we have on the people's thoughts are a few letters.
The regional differencies between various areas also would affect your situation deeply: rural Sicily was not the same of rural Emilia-Romagna; the countryside of Milan far different from that of Naples.
I have discussed briefly in this post the situation among the rural classes in Emilia Romagna. I hope it can be a decent starting point.
If you have some more specific question I'll try to answer those.
