I have been reading the threads you have posted, yeah your challenged with lack of transportation but if making a 45 min walk can indeed get you out and around people, maybe you won't find a guy but it would break the boredom of being stuck at home and feeling hopeless.
You are certain you will never find anyone <~~~ black and white thinking. There is always gray areas, that is where you will find a social and romantic life. It takes effort and work, its kinda like a job, well it all feels like a job to begin with, It's like interviewing people to see if you both make a connection friend or more than a friend.
I hope your able to make some positive things happen in your life
