<human>: Can you give me a shortened version of the text?

The title says it all. I'm 26 years old. I have my own place, a steady job, etc. I have a huge problem that is making it difficult for me to for any kind of relationship, romantic or otherwise. I'm extremely judgemental. I've always been like this. I always think someone is too irritating, talks to much, smells weird, is too unnattractive to even "bother" with. I HATE that I am like this. Its to the point that unless I'm at work, I'm usually alone. I tell myself, "wouldn't you rather be alone than spend your time with someone you don't like?" 

I know that its not rational for me to judge people so harshly but at this point its almost so ingrained in me that I do it automatically. I hate how stuck up and vain it makes me, like I subconsciously think I'm too good for other people. As a result, I'm constantly depressed and alone.

Im not sure what my problem is or how to even begin fixing it. I feel so awful even thinking about it. Any input from others would be appreciated.
<bot>: I subconsciously think I'm too good for other people and as expected, its having hugely negative impacts on my life. Advice welcome.
