I stil think the prime issue now is that its way too easy to distract yourself from your loneliness until its become a crippling issue. People can't spend 2 minutes on their own in silence. They have to reach for their phone. Play a game. Browse social media.
I have a group of friends that are all between mid twenties and late 30s who are making zero effort to meet women. They do a lot of stuff together and i know all of them want GFs but make no attempt to do it because its easier to avoid it and play computer games, board games, exercise together etc.
Time slips by and before you know it, its been years since you were dating and you have gone a bit perculiar. The people you are trying to date are probably the same or too well adjusted to take on a project.
Basically, turn off the phone, stop avoiding the discomfort and get out and meet some women. Its easier than ever in almost every way. There are apps, events, hobbies etc all of which allow you to meet women in whatever environment you are comfortable with.
