Suspected Candidia - colon cleansing

Hi

I moved countries 6 months ago and since then have had terrible stomach problems. Even after colonics an xray showed I was severely constipated. I tried everything, more colonics (open and closed), miralax, laxatives, castor oil packs, candida cleanses, oil of oregano, magnesium oxide cleanses, and now Oxypowder . I have found with each one I just keep putting on weight and especially with magnesium and Oxypowder - my stomach feels better but I retain kilos of water! The exception was my first dose of Magnesium Colon Cleanse - where I dropped back down to my original weight in 1 day - but only for one day as the following dose brought it back up again. I feel awful depressed, bloated, tired etc. The weight is actually just fat now and especially around my mid section, stomach.
Does any one have any ideas or suffered the same?
It is likely I am suffering emotional constipation (my father is terminally ill which is why I moved countries) - but I thought one of these products would help!

Thanks!
