Drowning in work and negativities.

I haven't been able to get good sleeps. Every night i try to go to bed but there is a feeling of nervousness and anxiety and i keep waking up to that. Its been terrible and i feel very tired. I can't get good uninterruptted rest and i think its really bad for me. I know this is ending in 2 weeks but thats the problem. I dun have good experimental conclusion, i dun think i can get a good thesis grade out of it. I feel like my thesis is as fucked as it can get. No doubt my group ppl tells me its ok as its part of science experimental research. But i feel that its not a good enough project to gimme a first class. Please give me the strength and courage to continue to finish my honours. I need a miracle to produce a first class.
