I used to suffer from anxiety and panick attacks a few years ago, thinkin I was gonna die every time I felt a pain etc! Well I got over all that evenyually. Then a few months ago I started my first cycle of Sust/Deca......well as soon as the stuff started working in my system I got paranoid as hell!! First few injections were done by a friend and that was scary enough, but when I did it myself I could hardly breathe and was sweating like a mutha fucker!!!
Anyway, the shit can make you pretty paranoid at first. I got really bad paranoid jealousy, not good, had some terrible thoughts and feelings about my girlfriend and what she might be up to! Absolutely rediculous now, we have an amazing relationship and always have had, but the Sust made me a little crazy.
The point is a lot of people feel quite anxious and strange at first, but it just takes some calm thoughts and reasoning in your mind to sort it out. Just relax, don't assosiate the pains, or whatever, directly to the gear and remind yourself your only giving your body more of what it produces by itself anyway, so it's not so bad really!
Stay calm and focused, we've all been there!
Good luck, and get ready to see some badass muscles!
