Finding new therapists can be so fucking tiresome because you have no idea if they can help you and you have to tell your story all over again.
Feeling like actually getting through now tough, hopefully, after having wasted like four years distancing myself from the past (=being unproductive, distracting myself/drowning thoughts with computer games and other things that invoke 'better' feelings, failing college, etc).
I don´t know if this even is of some use to you and I´m feeling like this shit is coming back up when reflecting about it but here are two things you could give a try:
1) If you feel like you´re drifting off, make yourself aware in the moment. Take a cold shower, pinch fingernails into your hands or just try to feel if the muscles in your body from feet to neck are tensed or relaxed. Watch a bad screamer movie like Poltergeist or Insiduous. Maybe have a wank or eat some nice food.
2) Try to make yourself feel secure, think of a childhood memory that was amazing and put yourself into that moment again.
Good luck :/
