How to stop crying

Happiness is a decision
For me making myself stop crying used to be by thinking is it really worth crying over..but my simple mind says yes so that fails..
Now its looking in the mirror..ikr..weird
But every time I do that two things could  happen
1) I laugh from how funny I look
2) I just stop and stare as the tears dry and I remain silent idk why that happens but it does

Then I thank God because really..crying just helped me clean my eyes to see better..to learn..to move on.. To avoid the thing that causes me pain..to pick myself up...be strong..grab the tissue..and wipe the tears away
