Loneliness Support Group
Loneliness is an emotional state in which a person experiences a powerful feeling of emptiness and isolation. Loneliness is more than the feeling of wanting company or wanting to do something with another person. Loneliness is a feeling of being cut off, disconnected and alienated from other people.

"Oh you went through that, then I can't be with you" .. it's a line of bullshit, I've heard it before myself.
I am in a similar situation as you, pretty alone in the grand scheme of things. Too much past baggage and trauma to ever be worth loving (according to one person I loved dearly).
I totally get what you're saying. But don't let your head lie to you. You're a valuable person and anyone who deserves to know you, the honest deep down true you, and to love you, will help you hold that so called baggage and lighten the load, especially on days you feel so heavy.
I'm hoping to find that myself someday. My arms are real tired from all this luggage. Hugs!
I don't think it is necessary to put on a smile and facade when meeting new people with the aim of a possible relationship. Nothing is more telling about who a person really is than what they do with their baggage.
Do they acknowledge the baggage, unpack as much as possible and store the empty (or near empty) luggage in a closet? Do they insist in lugging the baggage around with them constantly, asking others to go thru the contents on a regular basis. Having some baggage is ok as long as you don't expect others to carry it for you.
