I'll book an appointment with my GP. I think I'm more nervous to tell my mum about this than anything else. Feels like I'm disappointing her in such a huge way. The only highly sugary snack I eat on a daily basis are crisps and as sad as it sounds, I'm scared to let them go. My sleep is so disrupted now, I go to sleep between half 9 up and 10 and I wake up an hour later after sleeping to go to the bathroom and then when I do sleep I'm now very easily woken up noises (such as heavy rain the night before). This could be nerves and psychological, but I've never been like this before and it's all happened due to a small temporary change in my routine. At my friend's dorm I kept waking up at 7am even though we have were going to sleep at 1am and 2am and this early morning pattern has stuck even though I'm tired. Sorry for rambling, just worried. Thank you for your response though!
