to be honest not only you but i sometimes feel the same but trust me its not a good option i mean whenever you'll think to quiet your studies just try to imagine your future that how happy your family would be when you'll hand your first salary to them and this feeling is only gonna come true if you'll work on your studies:)
it's never easy buh it's worth the pain
bro I even paid my whole tution fees by myself. I thought the work I'm doing might be the distraction and I quit the job .. and till now I don't even touched my books... it is really painful..and I know what I'm doing is utter bullshit and by my inner me considering me as a loser and it's more like I'm starting to accept that...every time when I sit for study.. I'm not even able to focus... ** anxious about future..and many other 1000s of questions
honestly, you are not doing it, because you don't like it from your heart !! and forcing thyself will lead you to more misery, / according to there is some step you should take.
1.) Do that study because you want to do it try to take intrest, if you can't then every day try something that actually make you feel good , make yoyr fav. meal or do some creative stuff and 2) if you have some job with you can earn than you should think about what you skills(which you can find it in your passion) you have with that you can provide good service in this world and you can earn more so you can quite study completely
