Low self-esteem. Should I take a gap year?Watch
When you say 'year out' are you at uni or deferring entry for a year? If at uni, what have they advised? And it depends what you will be doing during the gap year. Don't need specifics but, if you haven't already, will you be getting professional help to improve your mental health? What else will you be doing?
After uni I took a year out and did nothing because my mental health was so bad. I don't regret it at all and I think it would have hit me a lot harder later on if I just ignored things and kept pushing on.
