I have problems with cellulitis and oedema due to me not being able to walk far

I have problems with cellulitis and oedema due to me not being able to walk far due to diabetic neuropathy in my feet and lower legs. I am currently panicking because I cannot get the cellulitis under control and keep having to have antibiotics. I am really scared because I also have made it worse because I reacted to something allergically and scratched my leg. Now the cellulitis is really worse.
I feel panicky because nobody seems to care in the medical world and just look at you as though its my own fault the diabetes is brittle and the hospital was going to support me by putting me on stronger insulin. I now just feel after waiting half a year that they are all uncaring and its depressing. I feel like I am the only one who cares what is happening and want it to go back to normal. I am 51 and have had diabetes for 30 years.

I managed to go and she gave me antibiotic cream. So I am taking oral antibiotics and this. I just hate how long it takes to shift an infection.
Thanks to you who listened to me yesterday. It was great support and stopped me being so scared.
I asked my doctor why but she just said nothing. And you know the hospital should be more supportive. In the old days they were so much more supportive. You never got left for months on end.Or maybe it is being in the city.
