Anxiety issues.

Help me! I’m finally gonna move out and live on my own and I’m scared 😭😭. I got an apartment on my school campus and I don’t know why everyday I have little panic attacks as I know the date is drawing closer 😩😩. I don’t know what it could be. How can I overcome this and be more positive??

Plus I have semi lived on my own but I’ve always had a roommate (sister or friend) but now it’ll only be me 😭😭😭
