I’m scared...

Okay so, I have to get braces and that’s not why I’m scared see due to quarantine my mom can’t come in just in case of any issue. And with me there’s many issues. I just got my spacers put in today but two fell out from the four I have I might have to go back and get them to put it back in? But I get the ACTUAL Separator thing for my bone whatever it is with the key? And I’m worried because nones gonna be near for support.. This may seem childish and it kinda is.. But I’m scared and when I see or taste blood I get highly naseous and I don’t want it to happen so I could use some advice please?..
