just me rambling into the darkness

I think for some, being alone, not having a SO is an intrinsic part of the reason for their depression. They then think how can others be depressed/suicidal when they have what would cure their own depression.

This perspective completely ignores individual cause and effect and is of course a fallacy perpetuated by limitations of their mind/knowledge.

I would concede that having a SO gives someone the feel of belonging, an ally to share their life with and possibly a source of financial and emotional stability. The support of having someone in your corner. I would also question though what role a SO has in fixing ourselves. Relationships should be mutually beneficial and roles should be evenly and fairly shared in turn.

Try not to feel guilty, it’s not justified. Pain is pain and can come from many places. It doesn’t always factor in what we have.

Even though you’re in a relationship it sounds as if you’re alone. Perhaps there comes a point where a relationship is no longer a support but a hindrance for both. Having found someone shows that you’ve qualities that are attractive to others, that feeling of joy not lost but gone with a time and person.
