From what I can see, there are two types of fear:
Fear #1
A "feeling" that is relatively normal response when we percieve there to be a legitimate threat to our physical or mental safety.
Fear #2
The "feeling" that is often ridiculously irrational. It is considered irrational because it is extremely probable that what we percieve as being harmful, is unlikely to ever occur.
Debilitating responses to fear:
1. Avoiding people and situations.
2. Immobilization. Do nothing, go no where, say nothing.
3. Irritable and combative.
4. Anxious & Jittery.
5. Panic
Both types of fear can be can prevent us from being happy, free, fulfilled and productive for the Lord.
I think it's important to understand that often our fear is triggered by being challenged to be courageous!
It's likely an indication that our comfort zone is worn out. It's time for the Lord to move us from where we are!
There are times when we don't need sympathy or empathy, but a good, firm, loving "PUSH" off home base.
For God did not give us a spirit of timidity or cowardice or fear, but [He has given us a spirit] of power and of love and of sound judgment and personal discipline [abilities that result in a calm, well-balanced mind and self-control].
2 Timothy 1:7 AMP
