Does the saying "Do as you please; as you judge, you shall be judged" apply to me, along with the fears it has brought upon my family after my repentance from my previous female escapades?

If a servant repents, regrets their past, and becomes righteous, Allah accepts them and forgives them. Indeed, He transforms their evil deeds into good deeds. The fear that the penitent person has for their family is unfounded after repentance. However, anyone who has a right over them may take their due from their good deeds on the Day of Judgment if they do not forgive them. Therefore, one must increase in good deeds to compensate for that. The hadith (definition) mentioned in the question is weak.
