Is it normal to feel that way??

As some of you might know, its still ramadan and I have been fasting! But something just doesnt feel right. While ramadan, I have felt very depressed and lonely, I can rarely concentrate on anything school related and I seem to lose my creativity. I feel like I was made for constant work and having stress a lot, which is unhealthy. But why do I feel specially like this on ramadan? And on the last 10 days before bajram???? 

I also came to the Realisation that only food and cigarettes can cheer me up whenever I feel lonely and these things give me the urge to go outside and study more, which sounds at first good but its kinda unhealthy. I think I am supposed to find something else that cheers me up, but I am stuck, I feel like I cannot go through all of this. I felt like constantly crying the last days and miserable. My sister wont listen to me anymore, she is so sick of me but I can’t blame her. 

Please let me know if youre familiar with this and what kind of sign it is 🫶
