Swearing by your family members is a major sin. It's shirk.
You should repent. Here is a good way to repent : Will my sins be forgiven
Allah is Al-Ghafur Al-Rahim which means Allah is the Forgiver, the Merciful. He forgives all sins if you repent sincerely.
May Allah forgive us all and grant us all eternal Jannah.
