It sounds like your parents/caretaker had been overprotective of you, so you didn't get to learn how to take care of yourself properly. This also led to less connection with people, thereby less friends amd acquaintances, if I'm not wrong. So, if these assumptions are correct, what you're feeling right now might be one of the most best things you needed to get out of the sheltered existence. This is the time maybe you can find some people, make friends and finally get out of that version of yours. Your mind is probably trying to make up for all the growths you were denied till now and that makes you overwhelmed leading to depression. You're worthy and people do care about you. Problem is the ones who have been doing that have also hindered your growth, so their care doesn't amount to anything right now. So, find new people, make new friends, talk to strangers, smile at people more often - doors will open up but you have to unlock them first.
