How bad is it to snort if you are congested and may have mild possible sinus infection ?

My nose was bleeding a couple times the other day

ive had this pussy stuff (not heaps) forming in one nostril for a while (way before snorting) have a really bad habit of picking at it which was already in my nose wayy before i started snorting but it is a little more sensitive

How much damage is possible if i continue snorting before it heals?

Im just experimenting snorting ritalin because im desperate to get some sort of feeling and have absolutely nothing else to take or do
