Distractions in class

Im super tired right now but im trying to blog more so whatever.

Yesterday we got a new seating arrangement in class and it was pretty ok because not a lot of people showed up in class today but today was terrible.

Not "terrible" as in boring or quiet, terrible as in I couldn't do anything because I was so distracted. I couldn't get any work done because my friends were talking all class and honestly its not their fault I get distracted so easily im mostly upset because of the seating arrangement. Though one friend wouldn't stop talking to me during lessons the day was mostly tolerable.

 Don't get me wrong I love sitting in table groups but teachers usually put us without or friends for a reason. Its also worse because now there is less of a chance of me talking to more people and making new friends. I hate talking in awkward situations and that makes it kind of hard to be confident around people I don't talk to a lot. I was honestly hoping to be in a table group with none of my friends because then I would have a chance to talk to someone without looking stupid. I don't have to walk all the way around the class to ask someone I've never talked to before about the work, instead I get to use table groups as a way to talk to people without looking dumb But the current seating situation has ruined the chances of that for me.

I also don't like being in a table group with my friends because we never do any work, I always get distracted easier and end up talking or drawing all class. It seems fun but it irritates me so much. Especially since I was finally doing good in class, and I know for a fact that things are gonna start going downhill now.

Honestly I would be happier even if we were in rows again or in rows with  6 groups of 2 and 3 rows of 3, that would be so much easier. 

my friends aren't the problem either its just one particular friend who I chose to sit beside (I regret that decision very much).

Its not my friends fault we cant focus together, but even he other two in our group are doing better than us. 

I need to start ignoring her when she does this. but its so hard to, she gets right in my face and keeps leaning over to whisper to me. I don't wanna be mean but sometimes I think she forgot how to shut up.

I wish I could ask her to switch spots with my other friend, but I don't wanna seem mean and I would feel bad. Honestly though what are my options at this point? tell her to shut up or wait for the next seating arrangement?

Honestly though even if I wanted to talk to her in class all she does is ask me about her crushes and what I think they think about her.

She is one of my best friends but I also think that she lacks personality and had become  the most boring person I have had to interact with in the past 14 years of my life, and I wish she would quiet down.

Anyways, advice on how to tune voices out and ignore people?
