Journal entries in a novel

I want to have journal entries describing what has gone on in the story so far (her therapist suggested writing everything down so far). In between entries (not every one) I want her to visit her therapist once in a while. This would be 1st person, present tense, b/c it's happening in the moment.

Should I use different fonts to differentiate the journals from the present day? Or do you think if I just put the time, date, weather etc. for the journal entry people can tell the difference between the journal and what's happening now?

Sorry if this is confusing. Thanks for any help or suggestions.

Good idea! Thank you.

Thanks for the input. I was confusing myself by thinking too much. (if that makes sense) I think I'll write one big journal entry catching the reader up to date, then continue ithe rest of the story in present tense. It probaby either still sounds confusing or unnecessary to do even that, but I already have 145 pages written and I'm trying to make the story more exciting. I kept feeling there was something missing. I came up with an idea, now I'm just trying to work it out. Thanks!
