bad runs

I have been playing about 2 years now mostly on-line SnGs and MTT.I have noticed patterns in relation to bad runs. When I started playing I hadn't a clue and didn't even know they existed but lately they seem too be getting longer and worse. Worse in the sense of bad beats. ie. During the last week I have lost several stacks pushing with the best of it only to be outdrawn by weaker hands, mainly inside straight draws. The questions I would like to ask are:
1. When this happens what do you tend to do? How do you cope?(Play tight, loose or just stop playing)
2. Do bad runs normally intensify and get longer?
3. Can you anticipate a turning point?
