Understanding the cause for my panic attacks?

Hi there, in the last 2 weeks i've been suffering from terrible panic attacks and anxiety. This started happening whilst I was travelling in Mexico. I was gone for over 2 and a half months but it wasn't until the last few weeks that I started feeling anxious. I want to understand why it has just come on like this. Can it be caused by traumatic events? There are 2 things which I think may have attributed to my anxiety. Around 4 days before I was due to fly home I was out on a small boat when a huge thunderstorm came over. Lightning was hitting the water around us and it was for me a near death experience. That evening after I drank maybe 3 drinks and in the morning had a terrible panic attack. From then on I was feeling constantly on edge and having to take valium to calm me down. The second thing is my fear of flying. I had come out traveling with a friend but she was leaving for another country whilst I was flying home alone. I never used to have a fear of flying but over the last year my anxiety about it has gotten worse and worse. Every time I thought about it (which was at-least twice an hour everyday leading up to my flight) I would just picture myself dying. It is the worst sensation to feel all of these emotions at once and I am finding it really hard to cope with. Luckily the flight went ok because I took quite a bit of valium and made friends with the person sat next to me. I honestly thought that when I arrived home back to familiarity that all of this would disappear. I thought that being with my boyfriend and friends would cure everything. But last night I had the worst panic attack I have ever had.(could be something to do with jet lag poss?) It was so bad that it didn't even feel like a regular panic attack, I generally thought I was going to die and had to call an ambulance to help me. It was terrifying. I am now alone as my boyfriend is working and I can't stop my mind racing and fearing what is to come next. Has anyone got any suggestions? Any ways to cure panic attacks they would recommend? I am also wondering about drinking. I had one drink earlier in the day before my panic attack and the day before that I had 1 drink and had the onset of one a few hrs later. It has to be related right? I'm only 20. I don't want to have to give up drinking for the rest of my life because of this stupid thing! I only drink occasionally maybe 3 times a month, but like to go for the occasional 1 drink with friends on some evenings. 

Any kind of response or help is appreciated, even just to talk to people who are experiencing the same as me.

Thanks

Wow. Fear often triggers anxiety. The lightening strike definitely would have done it for me. I assume you were on vacation?  Then knowing you had to come back to your problems once vacation was over could also be a part of it. If you are still feeling symptoms I would see a doctor and be square with him and tell him exactly what's going on. He should give you something for the immediate panic attacks and something for the long term disorder as well. But doing nothing will just make it worse and you will suffer longer. Thank you for writing and I hope you find relief

Thank you for the reply David, I really appreciate it. Yep the doctors will be the next step, i'm wanting to go today but i'm scared to go alone incase I have another one! Ah! 

I was in the same boat a week ago. Seeing my therapist for the first time. I was sick to my stomach with anxiety and worry before I went. Then I went and she put me at ease and was empathetic and caring. I felt foolish when I left because I had worked myself up so much before going there. I felt relieved leaving the office and knowing I finally found someone who understood. Fear of people, fear of judgement and fear of the unknown are all part of it. But we are stronger than this disorder, we are not children, we know in order to get better we need help so we battle through our fears and do what is necessary to survive. I felt and whole lot better afterwards and do won't you. 

Hi David, sorry I never replied to your message. How is everything going for you?
