That sounds like me a bit. the "clearly the problem must be me..."

I think for me loving and respecting myself enough is what I need to work on. Finding hobbies to occupy your time is a good suggestion, but it doesn't in and of itself cure the loneliness. It does help to build something of your own, that you could be good at, like art or music. Just examples.

We are made to find another soul in this world, we naturally long for companionship. Being all alone in the world with no one to talk to makes us feel hopeless.

I know though, that depending on another solely for making me feel less alone has not worked. I need to deal with the fact that I am alone, always. Even if you had that relationship you long for, you will find that you can still feel alone with that person.

This forum has been my main source to vent my feelings about this and my depression for years. I find it quite soothing to type out how I'm feeling. I can choose to take advice or not. I hope you find some relief in loneliness by coming here to post about it.

I don't know you so I'll ask if you have counseling available. I've found it sometimes helpful, sometimes not at all. Best wishes.
