Worried

I suffer from anxiety, insomnia, depression, etc. I’ve never self harmed in any way but I do go to a psychologist. The issue is I have an extreme fear of drugs and it’s because most of my family suffers from drug addiction. So when it come to taking something or prescribing something for my issues I over think as if I would end up like them. Everyone says it’ll help. So should I really be this worried. Does it actually help anyone?
