OP
honestly
as highlighted by others here, your fit was wrong, your situational awareness was wrong, and yet you put a title as “mining nearly killed in high sec”, which suggests that it is not your fault but it is the fault of game mechanisms.
I would kindly suggest you to read this kind of post where the author has, imo, the good behaviour: Stupid Person Posting This to Help Out New Players
Not whining, etc.
(and your english could really be better, but… ;))
