Uni for 3rd time, education history

I'm under the impression that it's best not to mention the dropping out in my personal statement. Would I be right that I have to mention it in my education though, even the time I was there less than a term? Do you think this is going to hurt my chances?

You must mention it in your education history. If you don't it is grounds to be removed from the application cycle which you don't want to risk.

It's not worth covering in your PS unless it somehow ties in to your motivation for the new course, e.g. a subject change where you realised your interest in XYZ. Much better to have your referee address it tactfully.

Difficult to say what impact it would have. It would certainly be of concern, however you have health issues which may mitigate somewhat. To be honest they would probably be more concerned if you'd started the same course twice previously. In some cases they might want to have a chat with you just to set their mind at ease, but it's going to be a very case by case thing as it is an unusual scenario. You may find that you get some offers without any other contact at all.

Appreciate the response. The thing is the uni isn't going to know about my mental health problems unless I tell them. Do you think it's worth contacting them directly and explaining. The thing is, even though I believe I'll cope better this time, as the entry requirements are lower than previous courses and it's a lot closer to home, I'm concerned they'll still just see it as a red flag and a reason not to take me. I'm thinking maybe I'll contact them, explaining and suggest an interview/meeting to talk things through in case they have any concerns. On the other hand I could leave it and try to contact the uni explaining my circumstances and requesting an interview if rejected.
Thanks
