If you don't want to do it, perhaps you shouldn't do it. RescueTime and similar tools/practices might well be just an internalized social pressure. You put on a mask that others want to see on you only to then helplessly observe your psychological immune system reject the mask through procrastination, depression, or whatever.

It is better to see procrastination and other subconscious work avoidance as a symptom that you are trying to divorce your actions from your inner motivation. Needless to say, such split personality isn't going to last and your inner motivation will win one way or another.

So fuck the work and do something you actually enjoy for a while. You will be more happy that way and chances are you will be more productive too.
