We had a small argument about something very stupid and I apologised to my boyfriend it’s been 5 days he’s ignoring me even after I texted him today. I am in deep depression. What do I do?

I understand it's emotional draining to not recieve a text back from your boyfriend. Give him some time he will be back to talk things out. The more you force it the further he'll move away. Try not thinking the worse of situation which tends to happen when your depressed. Think about the times you have had fights ans came out of it. You will get through this too, if possible look at it objectively and see if this small argument was the last straw to some bigger issue between you two which could be one of the reason he might be ignoring you. I hope things get sorted
