Stop worrying too much and this will only aggravate your problems. You really don't have to because all the problems you mentioned are curable. In the meantime , like the earlier answerer says, stop drinking and smoking and have regular meals. Relax yourself by doing anything that will make you feel relax. Since you have mentioned that you are going to seek professional help to overcome your depression, your problems will be solved after some time. Again, stop worrying too much
