Hello everyone! After giving birth to my second daughter, I've become very afraid of everything, I'm anxious all the time, and I always start panicking if someone calls, I immediately start thinking about the worst already creating bad thoughts in my head ??‍♀️My heart squeezes and cold sweat breaks out on my body, I think maybe from fatigue? Or am I just tired of monotonous life, we live with our husbands' parents, they are also negative people who constantly complain at the table, they talk about the bad news all the time. All day long then this doesn't come out of my head?What should I do, who can advise me?
