Body-type questionnaire

I wish to determine my Dosha so that I can eat correctly.  I have seen several questionnaires on the internet and do not know exactly how to answer the questions.  The reason is because I have been sick for over 15 years and I had a totally different energy level and physical condition and appearance than now.  Do I answer the questions from my natural and healthy experience of my condition right now?  I am located in northeast Tennessee and cannot locate an Ayurvedic person, and if I did, could not afford their advice because my husband has been out of work since last October.  This a lot to ask of you but if you have any advice on how I can help myself I would sincerely appreciate it.
