(apologies for dissecting - i'm bored)
What you mentioned seems all to be people-related...
Disillusioned, misunderstood, ignored and unheard
Its helpful to know the names of the feelings one is having ... not sure where "Disillusioned" goes, but have entered the other three.
I have had a really bad day
I've had 2-3 "bad" days .. due to suffering a toxic reaction to sth in house (which haven't found yet). So, sleeping a lot, waking with headache, having ZILCH energy to use computer (or do anything except watch tv). Quite unlike me. A hell of sorts - not depression, just depressed about life. I think when sth "goes wrong", then thats the rare time that i become aware of just how screwed-up i am & my life is; the rest of the time i just seem to blot-it-out with constant busyness, binging on comfort foods & alcohol, playing computer games, etc.
and right now I feel like no one gives a damn about me
=my usual state (mainly self-inflicted mind; thngs dont have to be this way, but i have "arranged" my life so that this status-quo remains)
I just wish for once in my life I could find some people that I could relate to
At best, i from time to time find people whom i can "relate"
somewhat, and for a short time - and then we
part ways. Even my with "best friends" over the years, i have only related to probably about ~75% at best. And only 1 or 2 friends have i kept permamently.
If that is a real goal you have (ie you
want to), then i think your best bet would be to find out all that really, truly interests you .. and try to find "places" (in real world, or online) where you can interact with others with this same interest; then over time you might be able to find people who have
other things in common with (ie like-minded) (?)
I feel like every single thought, belief and emotion that I have is incorrect or flawed. That everything that I feel is contrary to the reality of the world ... Even right now I feel like I should be apologizing for this post
I've very much had that problem on-and-off, for my whole life. It's like i feel
guilty or
"bad" if i am mistaken/incorrect about sth that i thought to be true, but which it
appears now not to be. But i have always been very wishy-washy & indecisive; might have sth to do with that.
I think its more about being "confident" in your own beliefs/assumptions about the world, than the actual truth .. as
WHO REALLY knows anything much about life??? I know that a few years ago i realised that what i "knew" about life was as good as knowing nothing at all, & in fact was
worse than, as i was committed to a bunch a stuff that "believed" to be true, but which i had practically no real evidence to support (so not any better than having vague, fuzzy, dogmatic assumptions)
: Sounds like a good risk to take, if it doesn't work out you can just think the same would have happened had you not, at least you tried. Good luck, either way everyone here will be here for you afterward!
