I feel like I should rewire my older trailer home , I don't even know where to start
Mia, I don't mean to panic you, but you really should get an electrician to inspect your wiring as soon as you can. If it's something  minor, you've taken a sensible precaution and gotten a problem fixed. If it's something major, you may save you and your daughter's lives.

There's a possibility that it's something serious enough to start a fire.

It sounds like you may have loose connections in your service panel (breaker box) or even loose or broken connections somewhere else, like in an outlet box or inside a wall. There's a chance it is a single bad connection.

If the neutral connection in your service panel is loose or open, you could get wildly fluctuating voltage on your branch circuits, as you turn lights and appliances on and off, which could burn lights out quickly or even cause appliances to suddenly catch on fire.

There's even a condition where an open neutral can cause current to "leak" into moist wood in your walls, which over enough time can completely dry the wood out and turn it into kind of a charcoal tinder, which is another fire risk.
