You should just continue being your normal self. Go do the things that you like to do and you may just meet someone who's interested in the same things and you could hit it off!

Never give up, because then if you meet the right person, you won't be ready...

Well are you happy with who you are? If you are not happy with who you are and where you are in life, you can't expect someone else to be OK with it. Look back at the last 6 years and any patterns that have developed. Repeating the same actions will yield the same results. 30 really isn't that old, and its never too late to change whatever you want.
Do something different, because that's the only way things will change.

This co worker friend thing, leave it alone. She is getting married and you have no right to meddle in those affairs.

Also if you start thinking you will be alone for the rest of your life, you will be. You will miss all the opportunities that come up, because you already believe they won't happen so you won't see them.

OK first thing you can do is stop with this 'i feel like giving up' attitude. Dude if there's something you want in life, YOU have to go get it. Have you tried going out and meeting women?
Work on your confidence, get some new cloths maybe change your hairstyle to something new that you haven't had before. Meet as many people as you possibly can, and do what you like in life, if there's a hobby you got focus on it, and you'll find that you meet more people and you'll meet more women.
You ain't going to gain anything if you give up! You reap what you sow, if you sit around being depressed all the time thinking that lifes too hard, then you'll achieve nothing!
Good luck dude
