It happens mate, just keep your chin up and apply for jobs.
Sometimes it takes a few sackings to get into what works and what doesn't.
My advice is to have a little break maybe scribble down some tactics, don't go looking for tips from others. Just keep it simple and it will feel great when you finally turn a corner.
If you go looking for tactical advice and then achieve good results it will feel hollow.
This is just my opinion though.
