To Go or Not To Go

My roommate just left for work and I'm alone in my room again. Sometimes I hate it when I'm alone because I get to think of a lot of things..too many things. Last week I've had an opportunity for a career change. I learned PHP in 3 days and though basic, yes, I've been able to code it. Then came our CompTIA orientation which I'm very interested in learning since it deals more on networking but would mean I'm stuck on my current job which defeats the "move on" and "time for change" motto. Just when I'm dealing with all these decision-making processes which I can't seem to make, you go ahead and give me a "surprise". Is it a good or bad surprise? I honestly don't know. I don't know what to think. I don't know what to tell you. I think I'll hurt you if I say "go" but wouldn't it be such a waste if I say "no"? Again I don't know what to say so I'd rather not say anything. You'll have to decide this by yourself this time. If you do decide to go, I will miss you and I'm afraid that I will miss you so, but I won't stop you.
