Should i be ashamed that i work as a cleaner?

So i went from a village to a big city abroad to go to university here, my parents couldn't help me with money because they don't have it a lot..
First i couldn't find any job! i was eating only bread and milk for some time and going everywhere by bicycle because i didn't even have money for a bus..
I was starving but didn't want to give up so i found a job as a cleaner..

Now my situation is kinda better because other than cleaning i work as a babysitter.. i believe some day i will find better job, i also go to university..

But when people ask me what is my job , their reaction isn't very nice..

Do you think i should be ashamed? should i rather hide it?
