I'm a PhD student meant to submit in 3 months but i don't have enough data. Up until very recently, getting an extension to candidature wasn't a problem but now it's almost impossible I've been told. So now I'm faced with either taking a 6 month leave of absence (no money) to buy myself another 6 months or just dropping out. I don't have enough for a masters. If I dropped out I'd be so embarrassed and my mental health would get even worse. I've spent nearly 4 years and will have gotten nothing out of it so I'm really devastated and feel like a complete failure
