Hey and welcome!
My first recommendation would be to follow the #1 rule of EVE:
Don't undock what you can not afford to loose.
Especially for newer pilots a bigger and more expensive ship is not always the better choice (and often there is a different, probably cheaper ship, that does the same job just as well).
Furthermore:
Every explosion is a learning opportunity. Trx to take away a few 'learning points' form every BOOM - be it your own or that of the others.
In this case I would highly recommend to not take your expensive ships into Lowsec or Nullsec for missioning until you are more comfortable with DSCAN and the specific rules of engagement of these types of space.
For more specific questions feel free to ask in our ingame channels, discord or right here
