Severus reached for the final ingredient left on his bench there was just the stewed lacewing flies left to add to his new potion. He stirred the liquid in the cauldron eight times widdershins and added the flies. The cauldron bubbled and the liquid turned lilac, eight more stirs clockwise and it should turn pale blue. He stirred and counted 1...2...3...4...the colour began to change as blue swirls appeared in the lilac liquid 5...6...7...8... success! The potion turned the pale blue he wanted and Severus let out a breath he had not realised he was holding. He smiled as he extinguished the flame under his cauldron. The first batch of his new anti-depressant potion was finally done, after two years’ worth of research, false starts and experimentation he had finally succeeded. During his own battle with PTSD, he had found that there were no specific wixen remedies for mental health ailments. The only real treatment available was muggle talking therapy. There were muggle medicines but they didn’t work for people with a magic core; there were no potions at all for depression.
