It's hard not to cry when such a drastic change occurs. And it's hard to stay positive. Don't push yourself right away. Cry for a while, cry it out. But don't cry more because there there is nothing else to do. There is a lot of things to do, and they could be as good as seeing a therapist for your well being.
I imagine your therapist have left you with some tools of dealing with your thoughts and emotions. Yes, it'll harder without seeing her in person, but what tools you have, use them. And yes, she is still there lending you strength, even though you can't be in her office. Just feel it. It's very subtle.
And we are here. And don't you know we are you, and you are us?
Please believe this. Your Therapist is not the only person in this world who can and would want to help you with your depression. You do not know where you may find these people. Though there is one place they are not, and that is in your bedroom where you are crying and so lonely.
And then, of course, there is that very old, almost forgotten cure for depression:love. Love others. Now that you, unfortunately, have the extra time, you can make a gift of it to someone else. Help someone, there is a lot of people for whom you, with your broken halo and sad face could be an angel. It'd wouldn't be COMPARISON that helps, not thinking "he/she is so much worse than me", no, not all. It is COMPASSION. Compassion is a great salve. When you open up your heart and gift your love to other people, or even animals it somehow helps you. It isn't even their gratitude. It is the giving itself.
Part of depression's danger is that it traps you with your sadness. It isolates you. But your heart has power to break that isolation. It just needs an opportunity.
Give your heart a chance?
