New here / types of meltdown question

Hi everyone

I am new to the forum here, and am waiting the final appointment for my autism assessment.

Having researched autism I am not sure I have had the types of meltdowns that others have experienced, but if a situation gets too much I just break down in tears.  This can be linked to feeling anxiety as well I think, but it feels a bit like a tap is running and as soon as it reaches the top, it overflows, and I start crying.  This can be troubling for those around me (my wife and children), though I have tried to explain that it is my way of dealing with things, and I feel as though ultimately it does help me, gives me a release.

I just wondered if others felt the same way or had similar experiences?
