Okay Mibba, I have a dilemma here....

I haven't been on Mibba much lately but that's due to the fact that I had my first full week of school this week. At first, I was excited about my senior year. My last chance to spend everyday with my close friends at my school, graduation, new courses, and a fun last year was what I was expecting last week. This week however, I realize that is not the case. It's clearly my fault though because I chose to take challenging courses and got accepted into them. (Some of which I was expecting/hoping to rejected entry into) After this paragraph I'll post my schedule below just to put it into perspective for any kind souls who would like to offer me advice on my dilemma :P It's finally Friday but I have senior portraits tomorrow and I have a TON of work to do this weekend. So, it's not really a break at all :/ On top of school, I start work on Monday and I have to keep my personal relationships in check as well as my sanity.

My senior roster
1st- AP Language and Composition
2nd- AP English Literature and Composition
3rd- Honors Theology
4th- Honors Latin IV
5th- AP US Government
6th- Lunch
7th- Probability and Statistics
8th- Honors Physics

My biggest mistake was signing up for both AP English classes :/ The huge amount of work I have for this week alone is causing me to seriously consider dropping some classes. I really wanted AP Language and Composition so I was happy that I got it, but now I'm starting to rethink staying in that class. So Mibba, for the supernatural reason that possessed me to do so because I cannot seem to make up my mind, I have come to you for help! I am thinking of at least dropping my 1st class. If I do that, I can move honors theology to 1st period and take the psychology/sociology elective that I've wanted since last year but couldn't get because of scheduling conflicts. I want to major in psychology and I haven't heard anything bad about the class so far. Physics is also difficult but I don't think I will drop that class. I like the AP Comp teacher a lot though, I had her for honors English last year and I'd feel bad if I just dropped the class :/ She's also the moderator for the Writing Center which I'm Vice President of, and I'm also President for another club. I put too much on my plate for this year and now I'm paying for it :/

I am so stressed out right now and it's really bothering me. I don't want to hate this year but stress will not make this an enjoyable year for me. Mibba, what do you think I should do? :/ Any help is appreciated <3
