Throwing up blood...and porn blocking

I woke up yesterday throwing up blood. I didn't really feel sick but had the overwhelming urge to throw up. I was kind of freaked out at the thought of throwing up blood. I spoke to my dad and my sponsor about it. It turns out they both have had stomach ulcers and have thrown up blood before.
Why would I have a stomach ulcer though? I am working really hard to live a life that invites peace. My sponsor said that whether I realize it consciously or not, I am going through major life change...and the stakes are high.
So, I have decided to do what I can to reduce stress: I am starting a workout routine this week, I am going to make sure to speak to God (out loud..for my benefit) about all of my cares and hand them over to him, I am meeting with a gentleman this week who will install a porn blocker on my phone and computer. ....anything and everything to assist me in walking down the road to wholeness.
P.S. I didn't throw up blood this morning, so I think things are looking up.
I will just continue to try to do the next right thing...Just for today.
