indeed, if you are in div I you should not fear.
When the newbie bonus is gone, you should have build up enough spectators for your games.
There also might still be a TV match sceduled for you. That money should get you trough the play-off season as well.
Just don't buy anything new (like you said) unless you can sell a player first and replace him with the money.
If you still lose money weekly, then something is horribly wrong, and you should come back to re-evaluate. But I feel you will loose your doubts within the next week or two.
Starting out is scary, I myself also panicked at first, thinking, this is not possible, but after I sold 2 or 3 players, I actually started to be able to affort prety much...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
