Is it normal for me to get these anxiety attacks... (help)
So lately I've been having this really bad feeling that suddenly hits me really hard out of nowhere... It can happen while I'm walking on the streets, at parties, eating or at home alone... Basically I become really nervous and frustrated for no apparent reason, my heart starts racing and I start to sweat, thinking about how much of a useless loser I am and how I'm gonna die anyway and nothing matters in life. Usually I'm pretty comfortably numb but this feeling has been haunting me for a while now, happens at least a couple of times a week. I even sometimes start crying if I'm alone but it's really suffocating to hide it when I'm in public. Today I was having lunch with friends and had this little panic attack, I rushed to the bathroom, threw up and started crying, but I washed up and thank god no one noticed a thing.
Please no religious replies, I'm an atheist. I just want to know if this is normal and if there's ANYTHING I can do to stop it other than medication... I hate drugs so much, they just make my life more miserable and I don't react physically/mentally well to them, plus I don't want to get addicted to anything.
