Have you ever slit your arm before? Like before the meds? I do not know a lot about depression but I know a bit about cutting and it feeling better for awhile. I do know that it can be a dangerous habit to get into. However if it is brought on by your meds you may want to change them as soon as you possibly can! Good luck!
Fully agree w/mammo. Try not to do cardio it raises heart rate & increases adrenaline. If your accessible to weights do them, they tire you more-suggested by my trainer. If not, go for along run til you cant no more. Most ppl take out their aggression in working out, good stress reliever. Do you know if you have other disorders? compulsions? Whats making you cry? Have you felt this way before medication? If medication isnt helping you coping contact your Dr ASAP, this medication may not be for you, possibly causing side affects.
I've had issues with sleeping, eating, and depression. The way I personally solved those issues was changing my environment. Are you unhappy with your life?
