    First off I apologise for the grammar I'm typing this on my phone also I want to apologise for the lengthy paragraph. Okay so I need to state this first I've had some axiety in the past but never axiety attack's before theses events it started at the end of March and is going on for almost a month. in my house when I was downstairs heating up food one night My brother thought it would be a funny prank to go in my closet and scare me! I'd went upstairs about to sit down and enjoy a meal until I heard the banging at the closet door (my closet has a window so I make sure it's locked and covered so a person or an animal couldn't sneak in) and I thought that's exactly what happened! I ran to grab my Survival knife! I thought I was either going to kill something or I was going to die that night! My brother jumped scared the hell out me from my closet thank goodness he moved out of the way in time because it could have ended badly with him in the ER. I then said "What the hell is your issue don't play like that I could of stabbed you" later he goes to his room thinking he had gotten me good! But later that night I started having heart palpitations, sweating,shortness of breath,tightening in the armpit area and some sharp pain around the heart/chest area plus, feeling like I'm going to faint or dizziness,some pain in the jaw as well. I could of sworn I was having a heart attack that night I was really tempted to call 911 but didn't I instead used natrual means (Green Juice,Magnesium Oil,Calming Scents, Breathing exercises,lavender) I felt a million times better but not 100%. Later the next day my brother apologies to me I don't hold grudges and I love him to death so I forgave him and he promised he'd never do anything like that again. The next 2 nights I felt the exact same symptoms as if I was going to have a heart attack and still did the same remedies. This has been getting better the past few weeks (my attacks have been weird some night's it feels like a heart attack, others it's "mild", and other nights I feel perfectly fine!) but occasionally I get the fear that I will have a heart attack or cardiac arrest or my heart just stopping In the future  I've talked to people and a psychiatrist and they say "If it was a heart attack or cardiac arrest you'd be feeling these symptoms 24/7" or "If you were having a heart attack or cardiac arrest trust me you'd know for sure, your body would definitely let you know if you have an unhealthy heart you'd would be bed ridden right now" or "your 20 years old it's very very rare you'd have a heart condition unless you eat extremely unhealthy or family has a history to heart dieases!" (my family does not and I don't have a history to smoking alcohol or caffeine! I'm not obese either.) Which this helps calm me down but I just want to make sure I'm okay and I don't want to become a hypochondriac. The axiety attack's have been going away a little bit but I'm a little worried because, Occasionally I do feel heart palpitations (that's the one I get the most), Some sharp pain around the chest (NOT as bad), and tightening of the armpit area without the butterflies and is it possible to have an axiety symptoms without feeling the actual axiety I didn't feel any of these things before the "closet jump scare" (sorry if I worded that weirdly). And what's even more strange is these symptoms only trigger at night (sometimes during the day and very rarely when I wake up but 9 times out of 10 it's at night or evening when I'm just chilling and absolutely doing nothing that triggers it!) However I will say my diet is pretty terrible but like the psychiatrist says "but not enough to give my self a heart condition, it's only in extreme cases" and ever since then for the past 2 weeks I have been eating a lot better (some trip ups but so much better) also my sleeping habits are out place as well I do stay up until 5am way to much for no reason (I should mention I don't usually have trouble sleeping I'd  sometimes get  butterflies that shock me out of my sleep but other than that my sleeping isn't too bad of an experience!) and try to exercise daily if I can sometimes at night and that "REALLY" helps especially cardio. I just want to say as of now it is the heart palpitations that have never been there until the axiety as mentioned before I still get those every so often when I'm not axious (but I have heard stories it can still affect you even when your not thinking axious thoughts!) sorry to make this sound really weird to but going to the restroom help as well! I just want to know if there are any doctors or nurses please any response would help or even anybody who has been through the same experience with tips or help I need some comfort or anything! I just want to feel 100% again or normal once again I know it'll take time but I'm totally okay with that any response will help thank you all for reading this and anything is greatly appreciated at this point!
