GAD roadblocks seem to be getting in the way of recovery

[Jtalia]

After being involved with a strict tech school, I gradually developed GAD.  I eventually got involved with Catholic Fundamentalism due to some fear, which only made my anxiety gradually get worse that I discovered that I had GAD.  I went through treatments with the "Linden Method".  The method suggested that I seek help if there are roadblocks still keeping me anxious

The problem now seems to be that everytime something unpleasant happens, I endure an abrupt change, get into a stressful situation or get angry, I return to a state of anxiety(disturbing thoughts, nervousness, ect.) 
abrupt change: getting ready to go on a vacation, starting a new class at school, starting a new semester.
Unpleasant situation: friend, relative or pet gets sick, someone you know dies, friend moves away, get rejected, your computer breaks down.
Stressful situation: Demanding class, overbearing friends or family, lots of work to do, ect.
I know that these situations are inevitable, but are there ways to be able to keep yourself on the road to recovery if this stuff does happen.
