Losing it

I think recently I have been tooo emotional and always losing it on little little things. I sometimes think I think tooo much. I think about getting married before I turn 30 but what if it doesnt happen......What should i do, to be honest I reallly don't know. What I know right now is to be happy in whatever I do. I will be off to east coast again next week. Realllly starting to feel old already coz i get tired easily and lethargic easily. realllly age is catching up on me sigh........
