Abilify seems to be one of the worst for causing akathisia as it is not typically sedating. Hence why i mentioned zyprexa and seroquel but if they are too sedating for you you could try risperidone if you really need a anti-psychotic. Risperidone is typically not very sedating and can cause akathisia I find that they help with the impulsive thinking for sure. I am glad that the lamictal isn't fucking up your head this time. I upped my dose very slowly because of the risk of that skin rash and this is what you are supposed to do.
I know it can be very hard to find a reason to get up out of bed in todays world. There are many days when the only thing i look forward to is getting high as well. But i do have long term goals and one of them is working towards a decent life for myself. Existential crises are common in the world we live in right now as even though we are more connected then ever through computers face to face interaction is lower then it was in the past for many people. Just sitting up in your room all day by yourself getting high is not good for your mental state that is for sure. Getting out even if it's only for a quick jog or a walk can do you a world of good. Finding something you like to do helps alot. I have to get out and do something or i start going nuts pretty quick. I live in a very rural area so unless you have a car you walk everywhere. So i do alot of driving around on the 4 wheeler i have. I also work out a good bit, read, go for walks and lot's of other shit to keep me occupied. I have to do something when i'm manic cause i can't fucking sit still!
Try and find something that interests you besides getting stoned and watching TV. No one is saying you can't get stoned (though i would strongly recommend laying off the psychedelics and everything but Cannabis until you have been stabilized for awile.
