Is AUTHOR wrong in the post ? POST : Side note before reading: I am pretty good at pretending (I'm in the theatre club at my old school) and have some decent manipulating skills, which I usually don't use for anything bad.

Backstory:

Over a year ago I became really depressed.
However I continued to pretend I was okay and for quite some time no one, except one friend (lets call him Tim) noticed. 
At the time, I wasn't close to him, which soon changed, because he started helping me and we tried talking to my parents about it (My parents are lovely people, who provide really well for me, but they are incredibly busy with work and our bond isn't that strong). 

Eventually, after having a breakdown, I started seeing a therapist. During that time, I learned a lot about showing others how I feel and started telling my best friends about my depression, though I never told them exactly what's going on. I didn't talk to anyone about my feelings except Tim, so everyone else just knew I was depressiv, but they didn't know anything else. 
When I tried to talk to my best friends about it, they usually ignored me or didn't take my problems with family etc serious, probably because they just didn't know any better (they were 16 at the time). 

Nonetheless, I was fairly honest about how I felt.

Now:

I came out as trans a few months ago and it went really well. I told everyone how great I am doing. However for some weeks I've been feeling incredibly depressiv. I kinda told Tim, but I made it seem a lot less serious than it is. 
I am pretending as if I am perfectly fine and usually it's not an issue, since my friends are busy with school and work, so I don't get asked, how I'm doing that much. 
Also I apologized to my best friends for lying and promised I'd change and tell the truth from now on.

Now one of my best friends texted me about her crush and stuff like that and I told her how I was suprised, she'd still trust me after how much I lied to her. She said, she had forgiven me and gives me a chance and how she's proud, that I'm trying so hard to change. 

But I haven't changed a bit. I'm still lying and I can't change. They had to go through so much, because of me. I was a real asshole while I was depressiv and they always Tim always had to care for me, I just really don't want to become this asshole again, I want to protect them from my depression, but now I feel shitty for lying and feel like an asshole anyway and since they don't ask about it, I feel like they don't really want to know.

Do you think I am doing the wrong thing? Or are my friends and family in the wrong for not caring a lot?
