Fear of abandonment and paranoia

The past two days I’ve really struggled to relax about my relationship. I’m sure it’s just in my head though right? The last time I felt this way my previous relationship ended. I’m so scared that this might happen again. But it’s all in my head right? I hate this feeling and it’s hard not act reckless. I’m trying so hard to relax and keep myself busy but I’m so anxious that she’s sick of me. She’s still on a psychiatric ward, coming up to three weeks now, and we’ve not had any quality time together. It feels like she doesn’t want to talk to me sometimes but I have to try and remember that she needs space and is in an environment where it’s not easy to feel affectionate. But it’s so hard when all I want to do is love her and be loved in return. Universe; please give me the wisdom to know what to do and peace of mind to cope with this. Give me a sign that she loves me please. I just need that extra bit of reassurance at this time. Thank you
