Massallah pertaining to a non Shariaah provident fund

I had a non Shariah provident fund which had 3 levels of risk, low, medium and high. Mine was medium and I use to give out lots of donation and my niyet was to cover the interest portion although I did not know how much. Then we were given an option of a Sharia compliant fund and I transferred all my money in there. The result was the income was very low because the fees were much higher and no interest. I was disapointed with the income because now I am giving less in donations. I decided to go back to the previous non Shariah fund. My niyet is to give some money to my domestic worker and others as donations. I would like to know if this is alright or do I have to go back to the Shariah compliant fund and share from there. I would like to do what is right according to Islam. I am a widow kindly please advise
