I am so mad at my doctor! i feel like he knew about the mood swings and just opted not to mention it! my entire life my friends and family have joked about how im always laughing and smiling no matter what is going on. i am a VERY happy person....i was just prescribed doxycycline for my acne and have only been on it for a couple weeks. i thought i was possibly having a pms problem but it just continued after i was off my period, i am so easily irritated now i find that i cry over nothing and cant seem to get over anything.this morning i got in a huge fight with my dad and was more livid than i ever have been in my entire life all over nothing!! and when i say nothing i mean NOTHING.i screamed at him and left my house and told him i wasn't coming home and not to call me or talk to me and then i drove around crying angrily and hysterically for 3 hours.my dad is practically my best friend we never ever fight.ive been losing sleep and having depressing thoughts about life and where mine is going.i just started college and im bummed cuz the meds are effecting my grades already(or so i think they are) i feel physically incapable of getting up in the morning and i have a hard time keeping up in the easiest dance class ever.i always have thoughts about how screwed up EVERYTHING is and my mom and i myself noticed that in the last week every time i call her its to complain about something and i get all choked up about whatever im talking about.now after reading about all these other people having issues with the meds im pretty pissed that my doctor didn't give me any options.if u plan on going to the dermatologist for acne i would recommend mentioning what you've read about this drug before they waste your time and money.life is too short for this crap...seriously.
