I rarely ever win over the negatives. Trying to think something positive instead doesn't seem to help because what I am feeling is the negative and I can't seem to fool myself.
I usually let it run it's course. fighting only causes exhaustion like you said and that just makes it worse. If I let myself just feel it, it will generally pass or not feel so bad. Coming here and talking about it helps (for example this last weekend).
