a little depressed

This has been a culmination of things. A lot of times I look at my ife and I think that what am I doing. I am 23 years old...work a part time job....and I still live at home. I do have my own car and pay all my bills but I always feel like I am just like a teenager, nothing against teens of course. It jsut seems like whenever I try to do something to improve my lief it doesn't work out. I had a full time job making good money with great benefits but I blew it. Just cause i showed up to work a couple minutes late. Something I had control over but blew. And then my relationships with girls I always feel like I don't deserve them cause of what I do with my life. Like because of this I am less of a man. i always think why would they like me...I'm a loser. them my Birthday was the 19th. One of my best friends didn';t even acknowledge that it was my birthday. granted I only know her as a online friend but we shared a LOt with each other and became VERY close. well so I thought anyways. The other one said "Oh he didn;t come to my party, why should i go to his?" granted I didn't go to his due to church reasons and some others, but that really hurt a lot. I know that without my other best friend,who is my CLOSEST friend, and Jesus I would not even be as good off as I am now, which is not to good.So if you could just pray for me I would really appreciate it. Thanks Rob
