Is it true the devil attacks you hardest right before a big victory?

I posted this before because I believe it is valuable information and worth repeating:

That mostly all religious pastors say, the devil attacks you before your victory or achievement.

Like I had an anxiety problem for 11 years from ages 9 to 20 and the year that God decided to cure me, I had the worst attack on my health and safety and life, I ever had in my entire life, it was so bad I did not want to live anymore.

But after that attack, God began to drastically reduce my psychological disorder and within months or less than a year, I had reduced my anxiety over 99%.

But part of clearing my old anxiety levels was that my old personality also had to get wiped out. When my previous personality was erased, I lost a lot of friends because they were no longer familiar with me and no longer knew who I was as a person.

I was basically in an embryonic state again with a totally newborn and totally ignorant self and no previous emotional history to conjecture or guide my personality or behaviour.
