There's likely meds you can take but to be honest in your case I would consult a Neurologist or at least an Internal Medicine Specialist. I sure would not let a shrink dispense it to me. In general I don't trust psychiatrist for treating such disorders as clinical depression or PTSD either. For more severe issues usually they seem to have their act together but on these issues it's here have a pill see ya in three months. They only treat symptoms and in general are apathetic or oblivious as to finding the cause.
I know what you mean by the symptoms though and yes despite what shrinks say one pill can do it. Antidepressants wired me out too. I had to go the tranquilizer route for relief. IMO a much safer way as generally those type of medications are short bloodstream life lasting less than 12 hours usually.
Benzapines class medications such as Atavan, Valium, Xanax, are actually counter agents or the medication protocol used to try and limit or reverse Serotonin Syndrome once it begins.
One more word of caution for anyone on any type antidepressant. Do not for any reason no matter how bad you feel take any unprescribed over the counter cold medications. This mixed with antidepressants is a known common trigger to developing Serotonin Syndrome.
