Sounds like you need to rent a husband.... but first, check for a reset button near the tank or pump area on a small electrical box . If yes push it for a second - do not hold it.
Find the electric panel that serves that pump area. Same deal with the breaker - turn it off and then on. Dont try and hold it on. Sounds like you need a new pressure gauge also.
Look for some references from neighbors for honest repairmen.
