Hi
I had gone through your query.
I understand your concern about anxiety.
Lorazepam is the safest anxiolytic for anxiety.
It has very low dependance level.
It can be taken up to 2 to 4 mg and with 1mg there are no complication like respiratory
depression.
So do not worry about it.
You can take 1 mg of lorazepam for anxiety but take your treating doctors advise.
Fentanyl is not used for anxiety and it wont help much in anxiety or psychological distress.
Mild dose of SSRI like escitalopram or peroxetine will help in anxiety.
Relaxation methods like yoga, deep
breathing exercise, meditations and
progressive muscle relaxation will help.
Stress free activities and identify stress trigger events, try to modify it.
Avoid smoking and alcohol.
Take proper sleep and diet.
I hope i have answered your query.
Wish you very good health.
Thank you.
