do you believe in karma?

I do believe fully in karma BUT that doesnt necessarily mean that because you (or anyone else) are experiencing continuous negative things you are getting Karmic payback....Maybe you just havent learned the lesson you need to in order to move forward and out of the rut you are in...

I don't believe in karma. The truth is the results of your doing. if you do good well you can expect many blessings from God. But if your doing is bad. what the results is also bad.

Absolutely, whatever you sow is what you reap and even if it doesn't come directly to you than it might come to someone who you love and care about. But I also believe that sometimes bad things happen so better things can come our way or because there is a lesson we need to learn.

He who sees inaction in action and action in inaction, he is wise among men; he is a Yogi and performer of all actions. For, verily the true nature of action (enjoined by the scriptures) should be known, also (that) of forbidden(or unlawful) action, and of inaction; hard to understand is the nature (path) of action. He whose undertakings are all devoid of desires and (selfish) purposes, and whose actions have been burnt by the fire of knowledge, him the wise call a sage. Having abandoned attachment to the fruits of actions, ever content, depending on nothing, he does not do anything though engaged in activity. To one who is devoid of attachment, who is liberated, whose mind is established in knowledge, who works for the sake of sacrifice (for the sake of God), the whole action is dissolved. Karma Yoga is that Yoga in which the person does not arrogate to himself the function of being the actor. All actions go on automatically. Let us first understand what Karma is, whose Karma it is and who is the doer. Analyzing them and enquiring into their truth, one is obliged to remain as the Self in peace. Nevertheless even in that state the actions will go on.

Prarabdha (predestined Karma) which created the body will make it go through whatever activities it was meant for. But the jnani goes through all these activities without the notion that he is the doer of them.
