Of course you can file if you're indigent. You can ask the court to waive your filing fee. Call the Texas State Bar Association and find out if there are any attorneys offering pro bono (free) legal assistance in your area. If you don't have any luck , it is possible to fill out the forms yourself. The forms are available online at your state's Federal Bankruptcy court website. Good luck.
The first step would be to go see a bankruptcy lawyer to discuss your situation, maybe payment arraignments can be made. If not you can do it your self and get the fees waived, Nolo press has a good book on doing bankruptcy yourself if that is the route you decide to take. http://www.nolo.com/products/how-to-file-for-chapter-7-bankruptcy-HFB.html?img=198&kbid=3615
