Should I continue in oncology, pursue UGC NET, or school counseling?

Ans: I am really very happy to see the positive mind frame of yours. I do think teaching ( i.e. College Teaching) will be the best job for you. At a time you and teach and counsel. Please don't be unsure about your capacity, from your writing it is crystal clear that you do have the required capacity to do M.Phil and Ph.D. Only your age is a bit high, because if you do M.Phil and Ph.D then it will take at least six years time and by that time you will be 35. If you are ready you can apply to some Universities of Germany for doing Ph.D directly. There M.Phil is not required. In Germany for ladies education is free. Only you need to have knowledge of primary German language for a smooth sailing. In school there is little bit use of Psychology, because the subject of Psychology is not there.
Your next step will be having a permanent job. Unless the basic needs are assured you can't concentrate. In India very few persons get job satisfaction. So if you appear for the state PSC exam, you may crack it, but Psychology won't be there, you may be a Deputy Collector or Sales Tax Officer with periodic transfer and lot of respect cum status. But don't be morose. Even being in other job you can give free counselling of Psychology online free of cost just to pursue your hobby. My basic answer is that first grab a full time job and then pursue your passion. Right now don't go for M.Phil and Ph.D.Higher degrees and age are proportional to each other. In last five years you must have completed M.Phil and started Ph.D. But no point in lamenting over the spilt milk. So two option 1) Do Ph.D from Germany 2) Grab a Govt or Private job which is not contractual. Take proper decision. That is the most important thing in career building. Never go for split mind and never try for true option. Make your aim fix and target it and I am sure you will achieve it.
Now just procure a permanent job and pursue your hobby of Psychology.Best of Luck. Prof. Mukhopadhyay
