Cliffy, you are a bitter old man with no redeeming qualities.
You would find life so much better if you smiled and weren't negative. The truly sad thing about your existence is that you don't have one. If your tablet ever breaks, you'll have no way to communicate with others.
You have no friends. Some people tolerate your immature behaviour on this board, but most don't, and that is why no one cares for you. Posting silly pictures and being contrary is the only thing you do.
Get out and socialize. Go to a senior's centre. Help out at a community kitchen, if your legs will support your weight. If they won't, get involved with something outside your apartment that isn't too physically taxing. Spend some time with children. Walk around your building.
Help others your age that may not be mobile. If it's hard for you to get around, phone the community centre and volunteer to help with something. Most communities have buses or volunteers that pick up people and drive them around.
Once you start socializing, your hatefulness will dissipate. More people will want to talk to you. You won't be a pariah.
If you aren't going to bother helping yourself, then find a ditch and throw yourself into it.
