Can’t talk to my Boyfriend, help!

So i have been suffering from depression since i found out my dad cheated on my mom and when he said he wants to leave me and have another child and make a new family, my parents both manipulated me a lot and they never loved eachother, i was the one who found out about my dads new girlfriend and son and told my mom, now they are divorcing and everyone hates my dad including her, he keeps breaking our heart but i can’t hate him because he still is my dad and i still love him.

I was so sad today at university and my friends tried to help me but they made it worse by telling me what to do and what not to do and stop overthinking and just be happy. It just made me feel worse about myself and weaker.

So i texted my boyfriend and he first he said to ignore my friends and that i am the bravest person he knows , but then he said my mom is more brave than me and he kept talking about me and my mom both suffering and being strong.

I felt not undrestood and i wished he would focus on my sadness when i feel bad not to tell me someone else is braver than me and is having a harder time.

I feel so angry because im such a happy person on outside that people think im just fine and they think just because someone cries more or shows more sadness the person has a harder time.

Im so angry at my boyfriend that i can’t even talk to him. Help me :(
