Obviously these are your songs, and you can decide how personal they should be. But there are two things to keep in mind. The first question is, who will hear your song? Will you be embarrassed if certain people hear it? If so, maybe this song is more like a diary entry, something to keep for yourself. The second question is, will other people relate to this song? Too personal is embarrassing, too general is bland. A good song should have a mix of specific and universal. Specific details are great because they make your song sound more authentic, and they immediately paint a picture for the listener. But then you need to relate your experience to the human condition. Your song could start with a personal memory in verse one, then become more general in the chorus. You could also keep the whole song personal until you bring in a universal message as a twist ending in the bridge or last chorus.
