Hi Blessed!
I relate to your desire to be a pastor. I decided at age 9 to be a minister - and from then on, I never doubted it; all my high school studies, all my work, was aimed in that direction. As soon as I completed high school I applied for, and started theology training. Three years later, I realised that I did not fit my concept of a minister. I completed my degree in theology, but did not enter ministry - I took further studies and entered teaching - and later nursing (then taught nursing in mission service in Africa for 7 years). More career changes until 5 years ago, the Lord spoke to me in meditation time, to tell me, "You've been running away long enough. I want you to come back to your first calling." I obeyed, and have been in ministry now for 4½ years, and though I entered it late, have never regretted it.
Why the long tale? Don't doubt your desire to follow the Lord; He promises to guide our paths if we are willing to submit to His leading (Prov.3:5,6). He may lead you to ministry directly, He may lead you via a detour (as He did me). In my case, looking back, I can see I was not ready to be a minister - dogmatic, argumentative, cocky, full of myself - no, the Lord needed to knock a few corners off before He could use me in ministry. Meanwhile, He used me in other areas.
So pray, study His Word, and submit to His will. Plan ahead, choose your high school studies to give you a solid grounding in English (and other languages if you wish), Bible, clear and logical thinking, writing and speaking, balanced with other general subjects. Check out the ministry training colleges that would qualify you to serve in ministry. Plan ahead - but always keep your plans before the Lord, and subject to His approval. God bless you Blessed! I'll pray for you.
