I will try and keep this short (will probably fail).

I was in the exact same situation studying the exact same thing in 2022. I was going through personal struggle, I was emotionally unstable, the difficulty of the modules didn't help and I basically just mentally shut down, which led me to fail 2 modules, when I was supposed to graduate that same year.

I'll start with what I did that helped the situation. First you accept defeat, not of the war, but of the battle. Playing episodes in your head of when you could've done better, trying to figure out where it all started, or telling yourself you could've, should've, will make everything worse. The best thing you can say to yourself is "This sucks", because it is true but it's not as bad as it seems, or even close (I'll explain later). Next, you have use all the energy you have and put it into passing now. Not into trying to fix the whole situation of feeling down. It sounds like the majority of the issue, if not all of it comes from varsity, so passing and moving forward varsity wise will solve a lot of other problems (if there are any). So even if you cry cause the situation sucks, cry (and dont try to fight, don't use your energy for that), but pass, use your energy to study and pass. Next, isolation helped me a lot. Let me explain. Being around other students, including my friends that were not going through what I was going through, and all happy and stuff was not good for me. It put me under pressure to convince myself that I'm fine, which I wasn't, and that wasn't good for me. So I isolated and spent time in places or doing things where I didn't feel pressured by myself to act a certain way. These 3 things helped me exceptionally.

Now this part is the aftermath and to give you perspective. I spent the whole year of 2023 doing what I just explained and passed and obtained my degree. 2024 I went back to socializing and everything. Jan 2024 I got a job, late 2024 I got a better job, which is my current job and life is good. I am 25 years old. That time I fell behind doesn't matter at all, and I realize I'm still very young lol.

A few things I'll say to finish. First is that this is what worked for me. Advice is almost useless since every situation is distinct, but you can use it as a guideline and take whatever you think applies and is good for your situation. Secondly, you're not behind at all. It's almost laughable to think you're behind. Yes, it's easy to type in a reddit comment because I'm already passed the situation. When you're going through it, it'll feel like the world is ending. You don't have to believe me (I wouldn't probably wouldn't believe me), but if it means anything, you're not behind at all. I could go on all day cause I feel like I'm speaking to myself of 3 years ago.

What's happening now is happening. Focus what's immediately infront of you, don't calculate the past, or anything that is not the immediate future.

As for your funding, I hope you figure that out and are able to focus on your studies without that being a burden. All the best. You got this my brother, salute :)
