<human>: We broke up the day after Halloween, but spoke again about a week later. He wanted to re-kindle things and I said absolutely not...but I miss him so much. 

Although I'm finally able to wake up before 2pm, every single morning I wake up feeling like absolute shit. I keep having nightmares where I'm chasing him and he's trying to get away or is getting with someone else. Every time I open my eyes all I can hear in my head is 'Suspended' by Kelis for some reason. It just sets me up for a bad day, every day.  

I can function socially and am able to sort of push it out of my mind when people are around, but I can't focus on anything which requires will power or self-discipline. 

I'm in my final year at university so It's vital that I'm able to function work-wise. But I just can't motivate myself to do anything. I've missed a deadline already and the next one's coming up soon. 

The only thing I can think of is going to the doctor and asking for some kind of anti-depressants. Are there any that anyone can recommend - any which don't make you feel like a complete zombie? It just seems like my only option at the moment cause the more I can't focus, the bigger the knot in my stomach gets, the more I want to contact him and the more anxious / depressed I get, the more I can't focus. 

I'm really trying to stay buoyant - going swimming, going to yoga etc  but it's just not working and I just want to hear his voice.

Summarize the given text in a few sentences.
<bot>: Break-up of 3 year relationship (initiated by me) causing depression, low mood & desire for contact. Unable to focus on vital uni work as a result - what can I do to remedy this?
