[Stressed]

Hello to all. I'm on a quest to get better credit. I have a few negative items on my credit report. Like 2, 30 days late and like 2 derogatory items that are in collections. I make pretty decent money. About 70k a year. I want to buy a how in the near future. But I can't even get a decent credit card. Now I have some good lines, with good payment history. It's just the bad history making me look real bad. I've read alot of questions and answers on this forum, but now I want to handle this on my own. Last year I paid a credit repair company, and they got like 2 things removed. Now I want to handle this situation on my own. So everyone wish me luck and I will keep everyone updated on the results!
