It makes me sad and tired to keep losing guys.
Do you have any idea why you keep losing them?
I lose guys because I treat them poorly
You need to be honest with yourself about why you treat your boyfriends so badly. You are chasing guys off and your reputation will suffer as a result. Stop being so selfish with others and give of yourself more.
But what if that doesn't work?
You'll never know unless you try it. If what you've been doing in relationships hasn't been working for you, then doing something different might be a good idea.
