Since you’re too scared to reply, I’ll try my best with no information from you: It depends on the DM and campaign. If the DM is doing a casual game or one-shots (adventures that take place in just one or two sessions), a lighter backstory should be fine. If it’s more grand or the DM wants to incorporate you backstory into the adventure, that have something you are comfortable with them using. Ask your DM what they want from your backstory and start from there. The Player’s Handbook (PHB) has pre-made backgrounds you can use as a base for your character(s). I hope this helps you.
