Scared of Serotonin Syndrome

Currently in the process of switching from Lexapro to sertraline. For the first week I did my normal dose of Lexapro (20 Mg) then 25 mg of sertraline. Then today I start to do 15 Mg of Lexapro and 50 Mg of sertraline for a week. Then continue on that schedule until no more Lexapro. When I first started the sertraline I forgot about serotonin syndrome. Last night I remembered it existed and have been in a panic ever since. I’m scared to start my new dose and I’m so scared and panicked about it. I know it’s very rare but I’m just so anxious about it.
