My current status

Well I've come from UK past 6 months now, returned to India for personal plans, confident that I will manage to get a job in India quickly...and still waiting to be hired. Initially I was playing it cool and infact also rejected an offer (which I still repent) but now I am taking things seriously and realizing that it is getting very very tough. I come from a s/w testing background with testing and test automation skills and excellent communication skills. I am also well certified in my area but I am finding it difficult to
a) obtain an interview
b) clear any interview
I see that I am unable to articulate my thoughts well, sometimes I am very nervous its not that I am not knowledgeable but i just go blank when i am asked questions
This gives an impression to the interviewer that I am not competent and they reject me

Nevertheless I am not gonna give up
1. I am planning rather have started maintaining a question /answers book and now intend to practice answering them in front of a mirror.
To tell you the truth..I've never struggled so much for a job, not even as a fresher and i feel humiliated with the thought itself.
2. Joined a gym and maintaining a routine in life.
3. My would be spouse is really standing by my side and keeping me positive.

you have any more tips or thoughts to share?
