I am so sorry to hear that you are suffering so much and that your stress and depression are continuing. You are dealing with so much and being there for so many that you are not able to stop and take a moment to care for you!
I can understand how your weight issues can make you feel even more depressed, especially when your medications are contributing to the issue. You said that you asked for a referral to a weight clinic. Did you get that referral?
At some point, please try to take some time to see to your own needs? Is there someone that you can talk to who is qualified to help you deal with your depression and stress? I think that it might be worth while for you to seek some help in that area because you cannot get your physical body healthy if you are emotionally unhappy. I wish that there was something tangible that I could do to help you, but all that I can do is to offer you my understanding and my caring! Please know that you can come to us at any time to talk about your feelings, we are here for you.
Peace and Blessings
Look For The Good and Praise It!
