I am a 24 year old guy, and I have that exact same thing. I had panic attacks when I was 14, and then went away a year later. Then, lately, 4 months ago, my heart would race, and now lately it would keep me up until 4:00 in the morning. Not so much anymore (I have good days and bad days), but you know how sometimes you kick in your sleep so hard that you wake yourself up? Well I do that and I've been kicking harder and harder, and it's like I gasp for air when I wake up, followed by (most of the time) shaking or being scared. At times, I wake up and I'm not really awake but definately not sleeping, and I panic feeling like I can't escape where I'm at, or that I can't escape reality (if that makes sense?), or can't escape my bad dream. Lately, I've been freaking out thinking about growing up,being old and dying, having a bad life, being alone or with someone I don't really love, or just living my life without being in control of it or disappointment. I feel guilty a lot because I'm more sexually active that normal (I fear getting my heart broken again, let's just say that, and I get lonely too), and all of this came I think by spending too much time at home during break, no job, and no school. I now feel out of it, sometimes I move my hand around or touch it a lot more just to make sure it's still there (lol) or that I'm still here. Anyone ever been afraid of thinking yourself out of reality, like pissing god off for taking life for granted? lol I feel so silly and so stressed out for nothing. But all of this is scaring the hell out of me. Anyway, just know you're not alone. I know life isn't to be taken so seriously, but my god it means so much to me.
