I hear where you're coming from, and yes you definitely have more going on for you than the typical neet I thought you were portraying yourself as.
Let me ask you this, how much experience do you have with women and relationships in general? I ask because I remain convinced that this a problem you have internally as opposed to externally.
You say you dont feel as though others accept you, why is this? What about yourself makes you feel and think that way? How do others react that makes you feel as though they don't accept you. If you're naturally content with yourself like you say you are, then people and women will sense that and be drawn to you, at work, classes, whatever the setting. So what about it makes you say that you're not accepted?
If you're at a stage where you have built yourself up and you are very content with yourself, the chances are good that you will find a girl to be romantically involved with, if you say you have all these things going for you, you likely talk to women often confidently and they sense your own internal confidence, happiness, and self-love which draws them to you.
The whole point of a romantic relationship is to share a life a with someone. But you cannot share that unless you are truly content with your own existence. It's also not necessarily about just external factors like money, career body, etc. Are you living your life with passion?
Because the truth is even if you become romantically involved with a woman, if you feel this way now, it's very likely that years down the line you will have the exact same feelings once the lust and hormonal phases have worn well off.
If you can accept yourself truly, others naturally accept you, unless there is something fundamentally wrong with you, in which case you probably haven't really accepted yourself
