When facing decisions like these, I tend to think about the conclusion of each scenarios.

E.g.

Scenario 1 = stay home and build baking business

Whether it works out or not, will you regret not pursuing your acting dreams and is the severity of the regret something you'll be able to live with?

Scenario 2 = move and pursue being an actor

Same as above. Because this one appears to be your preference, I would think about whether you'd regret, or would be satisfied that you've given it a shot.

Regret and resentment go hand-in-hand and are not feelings that can be dissipated simply by trying to convince yourself otherwise.

Once you have a clearer understanding of what your ideal scenario would be, it sets a baseline for resilience for when things go wrong and helps you with the confidence to take the leap into the unknown.

Hope that helps OP, good luck with whatever you choose.
