Hi, Woodsmoke. I know lots of people who are very sensitive about things in their own life and about upsetting things in the world at large...and they sometimes cry quite easily.
Imagine a big inflated tire innertube. If it gets punctured by something like a needle, the air will "leak out" - not in a big rush that flattens in quickly, but slowly. It might take a long time for all the air to get out. It might not even be noticeable that some air is leaking, at first.
Sometimes, if we hold in our feelings of hurt, sadness, confusion, anger for a long time, the moment something can start a small leak...since the leak doesn't get fixed, if something else also causes us to leak, we leak a bit more, and so on and so on. If the little puncture gets bigger, we leak a lot. Or if something sits on us near the little hole, there is added pressure from outside that makes us leak more.
I do not think you are baby or any sort of freak or developmentally challenged person. I think there is perhaps a lot of sad and upsetting things that you have kept close and quiet...and there's a little leak and when something triggers you (something puts more pressure near the puncture), you leak more feelings and tears.
@NYJmpMaster is quite right that maybe a professional could help you understand what is behind the tears. Sometimes good therapy allows us deflate that hidden innertube of feelings so we're not triggered to cry. When the innertube of our own "older stuff" has been deflated, we can often manage the new situations without older feelings surfacing.
