I just get frustrated because i don't understand how to make a difference.
and if 'not voting' as a form of protest, peaceful protest or whatever is ignored, then i don't know what you have left. do you know what i mean?
I do know what you mean.  I've always believed in voting, simply because we have the right to do so, but I do find it increasingly difficult to know 
who to vote for since it seems to make so little difference.  
I worry that not voting perhaps "lets in" more extremist parties - on the (questionable) assumption that their supporters are more likely to always vote.  Or it may be that a 30% turnout votes in exactly the same proportions as a 60% turnout - but I don't find any consolation in being one of the 70-odd percent who can say "well 
I didn't vote for 'em".
Violent protest is all very well as a "statement", but what does it achieve?  Who gets hurt?  Innocent people.  Policemen doing their jobs.  Even if you have a full-scale revolution (which let's face it, ain't gonna happen), someone has to pick up the pieces, someone has to get things done.  And they all end up being corrupted.
I think perhaps the only real way to make a difference is to play the game and enter politics, maybe as an independent.  The problem there is that independents tend to stand on single, local, issues rather than actually having a broad range of policies.  But maybe if enough strong-minded people stood on an "anti traditional party politics" platform we'd at least end up with serious debate in parliament and coalitions based on genuine good intentions.  It'd be a tortuous process though.   Not something I'd want to do!
