this is just my oppinion of my own suffering
1/i havnt got primary dp
2/my dp is caused secondary to anxiety
3/depression is caused for me by the daily routine of introspection and feeling 'unreal'
4/inner strength is extremely hard to find at first, and then when you run out of friends and resources to help you it just turns into a daily survival routine,and if you suffer from panic attacks & anxiety then im afraid that you just have to survive,its an unfair and extremely soul destroying way of living but its the only way,sure you can try and help yourself the best you can but inner strength will be found when you stop relying on others,its good to talk but take it from someone whos been through the run of the mill....friends and relatives will get to a point where they dont want to hear your problems anymore....so whats my point ?
you will find inner strength,you really have no choice in the matter
claire weekes does actually describe dp/dr in one of her chapters,ive read that book about a thousand times,and although im still upset that 'feeling unreal' and 'detached' was and still is never used as term by doctors and shrinks,dp is a secondary factor to anxiety....it might feel absolutely bonkers and foreign to you but in most cases no matter how frightening anxiety/depression is the primary problem is usually followed by dp/dr
this is just my oppinion and experiences
