<human>: Give me the gist of the text in a nutshell

There are almost certainly people for whom circumstances have dictated that relationships simply won't work for them.  I'm concerned this may be the case for me, regardless of how much I may wish otherwise.

  I'm disabled, albeit in a somewhat unusual manner; I have a metabolic disorder that primarily affects me in two ways, persistent fatigue and pain, both of which increase dramatically with any serious amount of activity.  The end result is that my body and mind work fine, just not for very much or for very long.  For example, walking for 30 minutes is fairly painful, for an hour or more it will hurt for over a day; I've spent every day for over a year improving my stamina up to this degree.  The bottom line is that I'll never be able to work or be particularly active.

  Clearly this presents problems.  My life is inherently boring, I simply can't do very much, I have literally spent about 90% of my waking life in the past 8 years sitting in a chair at home. This makes things awkward, I have to explain very non-obvious limitations essentially from square one. I'm *always* tired and *always* in pain, it's difficult for me to be expressive, or even resemble energetic.

  I've been on a single date in my entire life and it was an unmitigated disaster. Suffice it to say I overestimated my capabilities and was in traumatic shock from over exerting myself for at least half of the date, it was confusing for her and unpleasant for the both of us.

  So given this, I'm concerned that perhaps I simply can't sufficiently contribute enough to build a serious relationship.  I have been considering attempting to 'get out there' and seek a relationship but the effort would certainly be extremely painful for me, though I would consider it worthwhile if I were successful.

  Ultimately, I would appreciate your thoughts on whether a serious relationship is **realistic** for me, or if it may be more reasonable to forgo the pain and content myself with a single life.
<bot>: I'm permanently exhausted and in pain, could I realistically contribute to a serious relationships or should I just be content to be single.
