Start with some really light excersise even. Don't need to be sweating bullets. A few pushups even from your knees if you can't manage proper ones yet. It will help.
Also simply having a certain schedule of your day itself helps. Eat properly and make sure you eat roughly around the same times every day. Try to fix your sleep schedule too if it isn't the best right now. Might be a bit of a cliché but the whole "healthy body healthy mind" thing certainly holds some value. I doubt it will fix all your problems but it might just put you on the right track.
