Confusion, am I autistic? What does it mean? How does understanding my autistic traits aids making better sense of this world?

I am usually a very quiet person and happy just being with my own thought. I don't usually need to go out and mingle, but I can be sociable and friendly too if I have to (with effort). Recently, I suspect I may be autistic, usually, I am the one friends turn to when they need advice or a fresh perspective on things, in fact, Im almost always became close with friends during the time when they were most emotionally vulnerable (for example, there is this friend within a closed group, we don't really share the same interest, we just happened to be there whenever the group hangs out together, however, the frequency of us chatting outside the group increased recently, after her father diagnosed with stage 4 cancer, on top of that, she found herself overwhelmed in confusion with her recent engagement and increased anxiety over wedding planning stuff), probably bcz of my tendency to comfort other and a strange sense of obligation to reach out .

This recent realization of my ASD traits worries me a lot, I kept wondering what does it mean along the journey of pursuing my ambition, in addition to that, I have recently moved to UK trying to settle into a new environment and lifestyle, undertaking an extremely brain power taxing master degree. I can't talk to my friends about this bcz they are deep enough in their own ***, I wish there were someone who is mentally strong, who is capable of holding substantial conversation to talk to, to help alleviate some of my anxiety.

Who do you usually turn to when you are in dire need of emotional support.
