Itching and skin peeling. What to do?

From last one one year I was suffering from sores on my penis head. I took several kinds of treatment like bacterial,fungal and viral infection but I found no result. I was using tacroz regularly and it helped me in doing the symptoms but when I stop it, it again appears. But since last 1 month sores disappeared and and glans penis and fore skin started having inflammation and peeling on daily basis. Now my forskin's skin got so thin that I can't retract it and whenever I try I go through so much of pain it seems like it will crake down. And since one month tacroz is also not helping in this. Infection is increasing day by day. I am so much worried I am thinking of suicide now. I haven't got married but it may be next year and I am very depressed.cant think what to do?? I have tested for HIV for 2 times all negative, VDRL, herpes that too negative. Glugose is normal. It's been one year and I didn't get what decease I do have. Hope I can find solution here. I am very hopeful. PFA pics
