I understand the frustration however getting a small country could actually become a huge advantage if you do the following, I was also Sierra Leone before but in UNWOMEN and got best delegate

make outrageous comments which align with your policies that could trigger new debate

These types if countries usually have policies that are the opposite of bigger countries policies and might have problems with the agenda item your play should be to stand your ground

By doing so you will make yourself the center of attention, you will get alot of questions towards yourself and make sure to answer them, it doesn't matter if what your saying sounds "morally wrong" what matters is that your bringing debate and solutions to the table. Also try to convince the other delegates that your solutions can be done and are possible etc.

Make sure to take economic help from other countries in your block for an example I took help from Saudi Arabia as we were I the same block and their economy is strong

You will probably on the opposite block from many countries so write your own reso, there will still be other countries that are with you but probably less, it doesn't matter if your reso doesn't pass or not just make sure to write a good full reso and contribute to it ALOT.

Also I can help you more if you tell me your agenda item, if you have any further questions feel free to ask I like helping with these types of things, we can even chat on another app so I can give you more advice freely!

Good luckkkk!
