Take one thing at a time. Keep yourself busy with learning, doing an activity, going for walks. You said you are good at Math, you can try teaching on virtual platforms like outschool.com

Not sure where you are located. You can try joining a technology meetup near you, you get to meet people and learn something new. It can be a good place to learn about any job openings locally.
