Its certainly not abnormal..and I dont think you are going insane if you are crying all the time. Ive had times where I have cried for England ..in private and in public. Nearly always felt better after though
Sounds like you have not been able to release your feelings for a long long time and its no wonder you are crying uncontrollably now. It has to come out in some way. Is there sthg in particular that has triggered this release of emotions ?
I wouldnt be inconvenienced by someone crying ..nor would I NOT care if I saw someone cry. I would automatically want to know why ..even if I couldnt help.
So maybe this is a learned response to crying in public? Certainly if you have been around/raised not to show emotions because they are seen as an inconvenience/weak then I can see where its coming from ...so I can empathise. But I would question if your notions hold true for most ppl..
Your feelings are just as important as those around you...thats the point. No one should be in judgement.
See the tears as a breakthrough ..a way forward..a release from baggage..and a time for you to question old ways of thinking maybe..
All the best..
