UK General election, should you feel bad for not voting?

That's right another General election has been called after the start of brexit negotiations, its as if no one wants to tackle Brexit head on in hope people forget about it, but either way it's here and it's happening.
For the majority of you you will have been through the process before, for others it could be your first time, whichever one you may be you have to ask yourself " who will I vote for ".
Some will undoubtedly pledge their allegiance to one party or another, others might be changing there allegiance for the first time ever. Whether you're the former or the latter have you ever wondered whether it's worth it or not, do you ever feel you're only voting for one candidate because, well there less dangerous than the other.
We always get fed the same stories about how if you don't use your vote you're a terrible person, unpatriotic and fallen soldiers would be disappointed in you.
But if we're being honest there is a two party system in this country, Labour and Conservatives, I understand SNP( Scottish national party ) have a lot of politicians in parliament but there never going to get the majority to take number 10.
So if Labour and Conservatives are all we got, there's not that much room for diversification, If I'm being frankly honest I wouldn't want to vote for either of them, each have there pros but in my opinion both have too many flaws in their manifestos, both will add a ton of debt to the already unpayable national debt and both will continue to expand the balance sheet with their counterfeit Quantitative easing process.
These are a small number of reasons why I would hate to vote for either of them but at the same time, the argument for voting for the lesser of two evils always gets me, even when there are other parties that I would prefer such as the Pirate party that are in my district. Yet I feel due to the sheer size of that party my vote would be a waste knowing fully well they won't get a seat in parliament and are unlikely to make a difference without some sort of parliamentary voice to stick it to the top dogs.
Getting on to the point now, I was wondering from you guys whether or not you feel that this vicious cycle of voting in and out the same two parties that generally do the same things consistently for the past 60 years without making a major difference is worth people going out and voting. I myself will be voting for the second time in my life but this time for Labour, yet my sole reason for voting for Jeremy Corbyn is that he is anti-war, so if he did get in somehow but didn't follow through on his promise to end these pre emptive war then I don't think I could vote again for either party because the trust just isn't there, this article even extends to the likes of UKIP, Lib Dems, SNP and the Green Party.
Either way I'd love to hear if you're going to vote or not and who and what your opinions are on the importance of voting and whether it's all worth it.
