The Stress of it all!!!

So not only do I have heaps of assignments due the next 2 weeks but now I've found myself in the midst of an employment tug of war. My current job is alright I like it and it's in the middle of the city so close to everything, sucks b/c I have to work Mon-Fri though and I have class. Then yesterday afternoon my old employer called me and asked me to come back said they'd pay me more than I am making now. Only drawback is that A--I just promised my current employer I'd stay there through the end of November the day before. B--The other job is kinda far I have to take the train there and I don't really like working there but they told me that I could come back after I go home for 2 months and they'll pay more..uhh I don't know what to do and I'm under the gun just got a voicemail saying that they want me to start next week call to discuss my pay rate--dammit I feel like I"m being railroaded!!
