I have a few ideas; all I learnt from CBT.

Set yourself small incremental goals - and ensure you reward yourself for attaining them. Deconstruct any catastrophic thinking that might be happening (this can be done by listing out worst case Vs likely case scenarios Vs best case scenarios and considering the realistic outcomes).

Make a toolbox of coping skills for anxiety. A personal favourite is a bean bag 'weight' I rest on my shoulder which is comforting for me. You may find a smell to be reassuring or perhaps something tactile like a small stone to rub between your fingers.
