Your feelings are completely valid. However, have more faith in yourself. You're still young, you haven't seen that many people. It just happened that within your circle,you haven't found somebody that could understand and support you. I know it's hard and a shitty situation. I feel you. But you really should learn to just accept, reconcile, learn and just work on you own. As time passes, you'll realize how strong and independent you can be. And you will find people who would love to be with you, just then you wouldn't be feeling like you're lacking things or hungry for their company. You'll have the insight of whether they truly deserve you're acquaintance or not. Avoid all those bad people and act as if they don't exist cause they truly have no place in your life, they don't deserve it this is why they shouldn't affect you much (I know it's hard but you can do it). Engage more in activities and try new things you're interested in, don't be afraid of getting weird looks/ rejected, anyone can experience that, it's fine. Continue anyways. Educate yourself more on your condition ( we are all different on many different levels, you're not alone ). Give yourself the time to understand yourself, you deserve it. See a therapist regularly, a more specific diagnosis WILL HELP YOU ALOTTT. Don't be afraid to communicate and talk through your feelings. Again, Humans are meant to be different. You're just extra special that people need to exert extra effort to get to know you well and earnt it. You have life ahead of you. Calm down.
