Hi Alex,
Sounds like you are depressed,

like your meds aren't working. Also sounds like you have plenty of things going on in your life that would make a person feel sad or depressed.
I've had my meds stop working. I've also fell into the trap of because the meds were working well, I stopped doing MY work to take care of myself: get enough sleep, say NO alot if I have to - even if it makes me feel selfish or "bad", eat healthy, talk about my feelings to my doctor or someone who understands, go to a support group, or simply just remember to take time for myself every day, even if it's just watching my favorite TV show without letting anyone or anything interupt it.
I hope you are able to figure out what's wrong soon. Please take care of yourself.
