i can't speak for paranoia much but i deal and live with severe anxiety and my best advice is... give yourself some grace. i know it sounds weird but when you're in the depths of a panic attack or severe nerves you feel as if the weight of the world is on you, that everything's over. but the worst part is coming out of that and feeling so much guilt for it. and maybe that part's just me? but still, the part about forgiving yourself, i want you to keep that in mind. show some kindness to yourself because anxiety is a bitch and hard to get through and even harder if you don't go easy on yourself
