Should I continue CA?

I will be around 22 in feb & still left with grp 2 & it's a long way as after it it oc articleship then ca final, my future is at stake, the only reason I took commerce was for ca but I am regretting it. I am sure if I give my 100% will pass 2nd grp with exemption in costing & fm..., but the age factor scares hell out of me and how will I prepare for articleship as it's been long time I have studied grp 1 subjects.
