((((Reina)))) Yes, when I first started dealing with my mental health issues I needed lots of time alone for processing, for sorting things out, for figuring out who "I" now am. Your boyfriend is being immature. Not to mention not very empathetic and insensitive if he can't understand and support your needs right now.
Keep respecting your needs and taking care of yourself. You need support right now

, not someone else to take care of and worry about making him happy.
