<human>: I've had trouble getting along with my mother since I was a teenager at around the age of 14 and living away from home at university has been such a breath of fresh air as I only have to deal with the constant nagging over the phone. 

It literally feels like she can't leave me alone, and constantly needs someone to nag at. When I come home I keep my room clean, do my own washing and chores and yet still, she will find something to nag at me for. I know that most of the time, deep down she nags at me for my own good, as it's often about getting a certain job or sorting out my post, but her seemingly constant anger and dissatisfaction really, really gets me down. 

The nagging can at times be really ridiculous - for example I used to eat normally and she would nag at me to eat healthier and eat more fruit and veg. I became vegan recently and due to the change in diet, I've been eating lots more healthy foods. I told her that I'd eaten a cucumber that was in the fridge, and she responded by shouting at me because I'd "probably get indigestion" (which I did not). There really is no way to win her over. 

I've tried to patch things up with her many, many times and we've had the same talk about how I tell her she makes me feel sad and angry all the time and then she cries and apologises for being the "bad mother that she is" and then we make up for a day or two. 

I know that when I go home for the summer I'll be doing a few voluntary jobs a few days a week but I don't know what to do when we're both in the house together for however many days, as I don't have the money for busses to be constantly seeing friends/on days out etc. I do have a dad who I will be visiting but he lives at the other side of the country and none of my friends live there, so I usually get lonely after about a week. 

Thanks for reading this!

Can you condense the text into three sentences or less?
<bot>: Mother constantly nags me, it's gets me really down and I'm scared of moving back home from university for the summer as I'm not sure I can cope with the torrent of negativity. Any advice?
