why does this keep happening

this is probably the 5th or 6th time that Ive had a downswing of more than 125 bb in the past 7 months. What the fuck is going on? It seems like everytime I get something going and I feel like my game is on track I get hit with a bad beat on every hand I play. People have been trying to give their money to me at 6 max but the deck just wont let it happen. Everytime I have someone dominated they hit their kicker and everytime I have a pocket pair someone will have one overcard that hits. Everytime my AK doesn't hit I get checkraised and everytime I have a pocket pair and the board in all undercards I get no action.

I know variance happens but it seems that be happening to me way more than it does to anyone else. I just dont know what to do anymore.

Take today for example I lost $149 in 111 hands. I know this is a small sample but it pretty much sums up how the last 2 weeks have been. Here is my favorite hand today and this has pretty much guaranteed that I wont play holdem for another month.
