Just need some advice and support

Hi everyone hope you're all doing your best out there. I'm just writing this to put it out there, I've been studying in the u.k for the last 4 years now first visited in 2016 and now I'm doing my post-grad degree. I studied International relations with french in my undergrad and currently doing psychology with GBC. I want to work in childcare and education, or in social work with children, mental health, and things in that field. I've got a few years of experience working in the u.k mainly in retail and in schools in cover work. As an American looking at prospects to work and remain in the U.K it feels grim, I understand tier 2 and visa routes but honestly, I'm just lost and feel a little without hope? I've looked at going back to the U.S to do school psychology which is what my career goal is but I just have preferred living abroad and adapting to U.K culture. I've been looking at Scotland and plan on moving there in a few months. Essentially I'm on my student visa until the fall which at that point I can get on the 2 year postgrad visa but right now I'm just thinking  whats the point?

I'm riddled with worries and it's been hard enough doing a postgrad while in lockdown but without knowing what's next I'm barely making any progress academically. If anyone is out there and would give me any advice that would make me feel not alone or just dumb thinking and planning.
