A good thing i found to help me when i was really wanting to speak and finding it hard... was to write stuff down... key words etc... especially when stuff gets jumbled up...
Try not to look like a reporter though... that wouldnt go down well :o)
It does get easier though... i am starting to realise that... i just have to have faith and think i am not being judged... that may be the ego bit coming in... so i do try and share now...
Its getting easier to believe what i am saying too... because to begin with my head was so messed up with the lies it told me... that what i believed to be the truth wasnt alwas the case... now i have started to know the difference...
Keep going... and good luck
