I am a very optimistic, positive and fearless person and was really upset by my anxiety attacks, the suicide thoughts, the crying without an obvious reason and I thought it was so unfair since I just got married to the best husband ever and lived the life I always wanted. I talked to my doctor about it and she blamed the menopause (duh!). She gave me Lexapro and I'm doing great with it. I'm back to my old self and don't feel any side effects. I'm supposed to be on it for 6 months and then we'll see.
It could help you to write everything down and if you don't like to take any Rx meds there are natural remedies out there too. I don't have it handy right now but I'm going to have a look for it. You could do a search on the net too. Good luck! I hope you are feeling better soon and believe me you are perfectly normal b/c those attacks are a cry for help from your body and mind. Be happy they function that way. It's already a great thing you posted your problem here.
