Need some advice please :/

Not gonna make this too long. But basically i have hella trust issues. My boyfriend of 5 months knows this, and tbh is very patient and understanding. This month has been a little rocky for us. We both have depression and he tends to get these “flare ups” where he gets particularly bad. He shuts down and basically isn’t himself. Well now he wants more space, (we see each other every day, he lives across from me and he relies on me for some things) so he can gather everything. Well with my un-trustful ass, i cant help but worry and think he is going to cheat or doesn’t want to be with me and wont tell me and basically everything else i can possibly worry about. Its unfortunate cause i was slowly learning to build trust in him, but now its gone. To add, my boyfriend us very sweet and caring. Very attached and always wants to be around me. He says that its only a few days. Since i cant trust, i insisted that we take a break instead of space, and i explained the trust thing and he said okay. So Im coming here looking for any advice, nice or supportive comments or similar situations?
