First I never recommend therapy/psychiatry and antidepressants because it is harmful scam. Similar or even worse than Synthology and Jehova. The workers in this business are have nationalsocialist values and use often gaslighting and RAID method to catch you and cage you away. They get rich from this while their patients lose their health, homes, family, friends, purpose and everything.
Meditation is good but might not always be the most effective help, if someone has experienced trauma. For meditation it's really important to have a safe space where you can feel secure on your own.
The body always reacts to stress, sometimes even leading to organ damage or even strokes/heart attack. The best thing is often to get away from the stressful situation/humans and move to a better environment – although this is not always easy, especially if you are poor or lack a supportive social network.
For dealing with anxiety, medications like Xanax are often recommended, but they are all very addictive.
Personally, I would suggest focusing on physical safety, such as carrying a bodycam outside, big dog, and paying close attention to nutrition – eat foods rich in fiber, vitamins, minerals, and healthy fats, use supplements while keeping sugar intake low.
Healthy eating can support the body greatly. In contrast, drugs and medications often make things worse in the long run because medical/pharma lives from illness, weak humans and so on. Many humans who are on the antidepressants get very sick, they become fat and psychotic, if they try to not eat them anymore they can get epilepsy symptoms and have similar bad symptoms like someone who don't take his heroin/alcohol or worse.
