Just vote how you feel personally about the organisation of the EU itself.
I myself believed in Europe once, but am voting out for these reasons:
TTIP -

Secret plans for a United States of Europe already drawn up -

There are a number of other reasons aswell, but for me these are the main sticking points. I want the UK to join the EEA or EFTA at worst and am prepared to see Britain take some financial hit within the first 5 years if it means an end to the political union, but allows us to conduct trade deals with the other 160 or so countries as well as forming a trade deal with the EU, like Norway, Switzerland, Luxembourg and Iceland do and should after a while recover any immediate losses that resulted from leaving the EU. No-one can guarentee this as a certainty, though, but that's where the 'believe in Britain' rhetoric comes from, and I firmly believe this nation has the clout, determination and connections that will mean there will be no long term 'damage' to our economy or security.
Many in Europe want the Federal Europe and to do away with 'national identities' vis-a-vis the Soviet Union. Voices in Denmark and the Netherlands have stated that if Britain does leave, they want out of the EU as well. So at the moment there is no one side with a clear advantage in the debate and I can understand how annoyed about the whole discussion you can be considering how both sides have behaved. It could come down to yourself personally on whether or not you believe in the European Dream or stand by the idea of British self-determination.
