Your light needs to be a little closer. Place it where your hand gets hot then move it up gradually until it doesn't get hot after holding there for 30 or more seconds. If you ever think your getting a plant that is damping off, then sprinkle a little cinnamon around her and water in. This will stop damping off and is even a great preventative...
Put your light closer and itnwill stop them stretching, it is still viable at this point - just support it with a chopstick and it will sort itself out
