Anxiety and Panic

I've been living with anxiety and panic attacks for 18 years now. I just recently brought god back into my life. I sit in church and hear that fear is something we should give to god... and that I should let god handle these worries... but I'm having a HARD time letting god take these worries away. I could use some help here getting god to take away my fears and worries... so I may start living life again (worry free).
