Many autistics have a difficult time with interpersonal bonding. It's frustrating to say the least. Many don't have the oxytocin and vasopressin levels in order to be a "people person". As such, interpersonal relationships are more "scripted", "I should do this, that, and the other thing" to maintain a relationship. It can be mental work and we often need reminders, and we often fail. It doesn't come "natural" to us. As such, we are more likely to be by ourselves without a support system around us. This is the autism experience. It is more difficult for us. Now, if you are perpetually seeking validation and compassion from others, well good luck with that if you don't have a support system around you. You're going to be horribly disappointed in the reality.
Don't waste a thought on it. Envy, jealousy, depression, sadness are destructive emotions. Move on. Get your mind occupied with other things. It's a survival thing. It is more difficult, but also more rewarding knowing that whatever your accomplishments, it was because of your hard work, and not because you were propped up by others.
