Start small. Set little achievable goals and celebrate each win, no matter how small. This will build up your confidence over time.

Capacitors store electric charge in DC circuits, so they increase the voltage but limit the current flow. Inductors store magnetic energy in the form of a magnetic field, so they increase the current but limit the voltage change.

computer science is the safest option. you will have many job opportunities and flexibilty to change sectors after 4 years. Other branches may be too specific.
