1) With certain trigger points and events, I get really anxious and I also start being suspicious of everyone around me. I have medication which helps with this but I have people in my culture who tell me that it's not good to take them for more than once or twice because that will be sinful of me as if I do not trust Allah (SWT). These medications help me act normal and calm which also helps me focus on Islam because otherwise in times of extreme anxiety, I also fall into sins and forget about Salah. Am I being sinful by taking then more than once as people say?

2) Am I allowed to take this medication secretly without the knowledge of my family (if I'm in need of it) ? My family will not be supportive of me taking them and definitely do not understand the mental toll it takes on me. Medically speaking, the doctor says that I need it and should take it.
