Side effects from Cisplatin and etopiside

Hi i had my second of 6 cycles last tuesday and ive had the most dreadful bout of constipation. I managed to go after 5 days and i am now on a course of laxidos to help going forward. They reduced my dose to 80% this time and i habe not experienced tinnitus or vertigo as i did on first session. Ive lost nearly all of my hair too. 

I feel so down all the time is it normal. I had about 20 side effects last time this time its been lukd i say the constipation. Dreadful heartburn yesterday and a bit of neuropathy on the front of my hand. 

I am fearful of germs and catching infections but i cant lock myself away as thats no good for my mental health how do you recommend i try to manage or cope with this fear. Am i only one like this. I try to stay so positive. Any advice you could offer would be amazing.
