OP,
It's more than likely that at your age, a correct protocol and daily low dose Cialis will address you issues in no time at all. (I take 10mg/night). I'm the poster child for this. My issues started when I was about your age and now I feel almost like I'm a thirty year old again. Okay, so I'm exaggerating - like a thirty five year old. ;-)

My advice: Take it a day at a time and realize you're not alone. Once your start getting the proper treatment, you'll be astonished at how fast you'll feel improvement. It's very important to see yourself as related to countless others with the same issues - many of whom are on this forum. Out of tens of thousands, you're one of the fortunate few to have found yourself here. Stick around. Listen and learn. Then later on you can return the favor.
