There are many deep reasons for suicidal feelings & actions & sometimes we don't even acknowledge them at the time they are happening. To give specific reasonings for someone feeling that way negates other reasonings that can actually be there underlying it all. We have to be careful when we say "this is how people feel when they have those thoughts" I didn't even know that trapped feeling was the cause until after years of good therapy & going back & analyzing my thoughts. Be careful limiting the reasons for feeling that way
