Heya
Stopping the meds and starving yourself is going to do you no favours whatsoever. The effects from stopping the medication is obvious - the starving yourself not so much. One, you'll lose weight, sure. BUT you are also starving your body of vital nutrients which is enough to cause mental health problems in itself. When fighting these issues, your mind and body need decent nutrition to function properly, and without that, your mental state will only get worse. Also, though you may lose weight initially, you'll gain it straight back. Your energy levels will drop through the floor. When you starve yourself, then you start to eat again, your body will store everything it can in preparation for the next time of famine - leading to more weight gain. It's a vicious cycle.
I have had problems with eating disorders, and now I am eating properly, I have the devils own time keeping my weight down. The annoying thing is before this all started, I can hand on heart say I had a lovely figure and wasn't at all fat/overweight.....just my broken self esteem told me I was

(well, and a very charming ex husband did too *spits* )
So, here's what you do. Firstly, keep taking the medication - the doctors gave you it for a reason, you need it. Secondly, Eat healthily. Don't meal skip. Watch what you're eating, eat slowly, chew everything and stop when you are full. If you eat too fast, your body doesn't have time to register that it's full, and will lead to overeating. If you get hungry between meals, it's so easy to grab a cookie, or a packet of crisps...don't. Grab a piece of fruit instead. Junk food is empty calories, with virtually no decent nutrition which you need at the moment.
Eat good quality proteins, (lean meats,fish - including oily types, pulses, beans) rather than processed hams etc with every meal. Carbs are needed too, but since I have gluten problems I tend to go for vegetables rather than the grain types such as pasta and bread.
It might help for you to keep a track of what you eat on a normal day and calorie count it. It's easy to snack our way to well over the intake we need. Don't get obsessive over this, just do it for a couple of days, register if there's a problem, alter your intake to a healthy amount, then stop doing it.
Set a day of the week to weigh yourself, then do it only on that day. At my worst I was hopping on and off those scales several times a day. In the end I needed to throw them away, but I have since bought another set which gets used responsibly

Exercise. Yep, I'm sorry. I had to say it. I was never one of those lucky people that loves exercising but we all need it........especially those of us stuck in a mental rut. It doesn't need to be going for the burn (although kudos if you can do that - I'm far too unmotivated, or should that be lazy

).....even an extra thirty minutes walk in the park on an evening is better than sitting watching the tv. It keeps the metabolism ticking, raises seratonin levels, and whilst you're doing it, your thoughts are not going around in those nifty little circles that drive you insane.
Monitor your self-talk relentlessly. If you notice you're getting into an obsessive thought pattern, change the subject. Do something absorbing, something you enjoy that needs mental input - crossword puzzles have been a lifesaver for me many a time.
Well, I hope that's been a little help somewhere at least. Now I'm going to take my own advice and go for a walk, because I'm feeling a bit yucky myself today. Good luck :)
