It's times like these that we feel the value of our senses. If you remove a sense, like the sense of touch, it can be deeply impacting. Some of our relationships are such deep sensory experiences.
This is going to sound a little outside the square but something that might be worth considering is replacing the direct senses of touch and smell of your boyfriend with something he can post to you. For example, just say he posts you a teddy bear. Before he posts it to you, get him to sleep with it in his bed the night before so the bear picks up his smell or maybe he's got a favourite aftershave he can spray on it. So, next time you Facetime each other, you're holding something he's held. This connects you. You won't just see him and hear him, you'll be able to smell him and connect through touching something he's put his touch into. I know it won't be the same but maybe it will help tide you over until the lock down ends. Just a thought. Maybe this idea triggers a better alternative, also a little outside the square perhaps.
Nothing completely replaces a loss of sense that we directly connect through with a loved one. Wondering about the next best thing can be a way of managing.
How someone makes us feel is highly significant, especially when we're facing challenges in life. We don't always realise how we feel our way through life. We see someone we love and we can feel our heart race and we might even feel those butterflies in our stomach. We can easily fall in love with such a feeling. Seeing them, when we're anxious, can lead us to feel a sense of 'powering down', as our body goes from extreme hyperactivity to a sense of peace. We are able to feel peace, in this case. Maybe this is something you can experiment with during Facetime. Pay attention to your physical/emotional feelings. Even though the physical distance exists, another way of connecting can be through the sense of feeling how you connect to your partner.
Yes, living in Melbourne is definitely a challenge at the moment. Figuring different ways to connect with life is one of the greatest challenges, I believe. I find a lack of excitement deeply challenging but I'm determined to be up for such a challenge. I will not let these times get the better of me; I will use them to find the better in me.
Take care and look after yourself as you face this challenge :)
PS. Wondering if you've advised your family that you're extra sensitive now, without your partner's direct presence in your life.
