This is specifically to the OP, but also others that have generalized anxiety. Counseling can be very helpful and hopefully many can support remote sessions. From personally speaking, what I also have found has helped:

- trying to be helpful to others - this single mental attitude can improve overall mood, make one feel more connected, and has a positive effect on the world

- have hobbies and activities that are engaging and that you look forward to. For me this is boardgaming, which has been a bit of a challenge given the social distancing, but fortunately there are online options that are helpful

- reminding myself that this is temporary. Although I haven't quite been through anything exactly the same, I have been through difficult experiences in the past and have grown due to them.
