Hi there.
Sounds like you're under a lot of pressure right now. You've stated that thinking about university has given you anxiety in the past and this has come back with the looming of results day. I'm wondering what is it specifically about university that is making you feel worried?
I think this is likely down to the instability you have experienced in the past. Almost like you finally feel as though you gotten your life settled, and you're worried a drastic change like this may disrupt everything and cause it to slip out of your hands. Is this mostly just with regards to your relationship, or are there other things?
Although you come from an immigrant family and nearly fell into homelessness, this cannot be a reason to force yourself into doing something that could ultimately worsen your mental health. Health should come first. If you often find yourself in tears just thinking about moving away, I fear the reality would be much worse.
Education is definitely important and it sounds like it is also important to you. It sounds like you've done some digging and already found some great options that get you where you'd like to be in terms of a career. This is really good to hear.
Despite all this, there's something I'd like to flag up. You said you cried on the first day of your holiday due to being away from your boyfriend. To me, this indicates a bit more of a serious and likely deep-rooted issue. It's normal to miss those we love, but being away for a time that you know is only short-term and being this upset can often be a sign of an attachment issue. You did mention you both suffer from severe anxiety, which honestly, may be creating a destructive relationship dynamic. Sometimes two people in a relationship can help each other with their mental health, and other times, it can end up taking a toll on you both without you realising it. I hope you have both reached out to professionals seperately for some support.
If your boyfriend is the main reason stopping you from doing something that would really benefit you long-term, then you may want to do a bit of thinking about how often you're affected by it. It may be that you need to speak to someone.
I think it's likely that university right now would do more harm than good for you. While exposure to things we fear can be helpful, sometimes it makes us a lot worse. You should begin university, if possible, with a healthy mindset.
Please let me know if there's any other hindering factors that you can think of. There may be more to it that you haven't mentioned, but the fact that your relationship was the first thing you wrote down is a bit of a telling sign to me.
