Help me stay in the UK and continue my studies

I am a recent Law graduate and the covid-19 pandemic has left me in a difficult situation where I am unable to return to Trinidad due to border closures and so my only way to stay in the UK at this point is continuing my studies. However, my funds are limited and my parents are no longer able to support me.  I have applied for a masters in International Relations at my current University and almost certainly have a chance at acceptance. It will be part time as it is cheaper for an international student however, I still need to pay for my visa on top of my fees. If I am able to pay for it in full then I would be able to get an alumni discount which make the cost a bit more reasonable. I usually never like to share my personal life and problems for the public or ask for help but I am desperate at this point. My current visa expires on the 30th September and while I am able to get an extension, it is not permanent and I am looking to stay here so I can start my life and achieve my dreams.  My family are currently stuck in the Middle East at the moment unable to get home as well and all their funds are being spent on supporting themselves there. Staying here would be the self start I need to getting back on my feet. The government of Trinidad and Tobago has not been very helpful and communicative in their repatriation process if citizens and many of us are forced to look for ways to support ourselves in an inconvenient situation. I have lived in the UK for almost 5 years and my life along with my partner is here. To be able to stay here and study my dream course would not only be a dream come true, but also my only way out of a very difficult situation that has negatively affected my mental health.  Donations small or large are welcome but a simple share or retweet would go a long way. (Donations will be collected by my boyfriend Martynas)
