physical is easier than the emotional

The physical is definitely easier than the emotional. Recently I've been having that feeling -" omg, I'm 23 years old" kind of feeling. It's not that I'm feeling I'm really old or anything. But rather, I feel like I haven't been able to test myself to the limit. I'm at this age and I still have SO many question about myself. I guess what question that I'm refering to in specific is my ability to commit to. nother human being. I "thought" that I was ready, I even told a friend that I'm ready. But last night it hit me, phyically I may be ready BUT honestly can I commit? Can I be in a relationship that will probably require most of my time and emotion? Can I do all that and not give up the moment it gets tough? I often think about that ... I think emotionally I will have a struggle and it definitely will take a toll on me. I know alot of people say, you'll never know what you are capable of until you meet the right person. Maybe... just maybe... I guess there's just no way to be sure.
