Stir up the gifts of the Spirit that God has given you.  Ask God to put an intestinal fortitude within your soul that stirs you to Get Up from where you are and Do what you can with what God has already given you.

If not now, then when?

If not you, then who?

Faith requires action.  God will do what you cannot do and He requires you to do what you can.  Get Up, Get Going and Watch What God will do though you.
