Hi on another thread I posted about weight gain. I had to gain a huge amount and felt often very sick and in pain but had to do it. Food is medicine and can really help with depression,pain,sickness. Its so hard in the short run but in the long run can give you a better life. I really think a nutritionist because I would of never been able to eat the amount I needed and they can help establish a taylored plan and also with the mental. Take care.
