Why do i feel the need to be in constant touch with people? ?

Of course not. It's good you always have time for your friends. My best friend is ALWAYS busy on weekends, and trust me it's not a good sort. If your so busy, people won't put up with you. But trust me, there will be a day when you can't come to an arrangement, or you've got loads of work to do. The texting at work though? That's got to stop. You're at work, and you can easily text/call your friends later. This is all a case of setting your priorities straight. Write a list of the most important things to you, eg; friends, family, work. & put them in order of importance to you. :)
