What to text when she says she's juggling a lot right now

A line like "juggling a lot right now" tells you two things. The first is the literal one: her calendar is full and replies are the first thing to slip. The second is that she felt a need to explain the gap at all, which means she noticed it and cared how it landed. That second part is the more encouraging read. People who are checking out usually just stop replying and do not bother narrating it.

What you cannot tell from one message is how long the busy stretch will run. Look at what she offers. A specific timeframe like "a few days" or "after Friday" means she is giving you a rough return date. A vague "sorry, so much going on" with no end point is less informative. Either way, the reliable read comes from her next message, not from the one you are about to send.

Your reply has to meet her where she is. She has just told you she is stretched, so the most useful thing you can do is make replying easy. Acknowledge the reason in a sentence, with no sympathy speech and no advice about her workload. Then leave something small and open that she can answer in one line whenever she gets to it. A question with a simple answer works. A reference to something she mentioned earlier works too, as long as it does not require her to recall much.

The move to avoid is making her feel she owes you a full reply to make up for the gap. Keep your message complete on its own, so silence afterward costs her nothing. You are telling her the door is open and that she does not have to rush through it.

Send your reply during a normal part of her day, not late at night when the thread looks like a fresh chase. A message that lands at 1am after she apologised for being slow reads as eager in a way you probably do not want. Mid-morning or early evening, on a day that is not the one she said was the worst, is usually safer.

Give it time before you send anything else. Two to three days is a reasonable window if she gave you a timeframe, and a week if she did not. If she has not answered after that, send one short, low-pressure check-in that adds nothing new. Something like a light reference to the thing you talked about, with no question about her availability. If that also goes unanswered, stop for now. Leave the match or thread alone for a couple of weeks before you consider reopening it, and if she comes back, match her pace rather than making up the lost time.
