So i'm going to start of by giving you a bit of back story. At this moment im 16 years old and have 3 siblings all of which are younger than me, for the past 3 years my dad has been suffering through depression (kinda) and it is starting to get on my nerves (hear my out).
3 years ago my dad had an editing job which he had had for the last 15 years, it payed well and supported us well as a family in my eyes, my mum even stopped working so she could look after my and my siblings. As of 3 or so years ago my dad has quit that job ever since my mum retrained as a midwife and perused a job in research (a midwife is someone who delivers babys), i guess he was kinda inspired by what she had done and how much she enjoyed her new job (his friends from his old job had quit so he was not enjoying it, beginning to get depressed and have a small drinking problem) she continues to do it to this day. So my dad took a while to decide what to retrain as (my mum was kinda forced into working alot so we could still have enough money while my dad did not work), he settled on being a teacher. He started a course in teaching and after about 6 months of doing that it made him depressed and he quit that (even though he had already payed alot of money for it), he again took a while off doing nothing and after a while he decided he wanted to peruse his teaching dream again, it took the people about 4 months to be able to get him back on the course from where he left off and he only had to pay a little bit to finish it, during this time i noticed that he was very sad and drank a bit more than usual.
About 6 months later he finished his course and he has recently started a job in a primary school, he has finale achieved what he was trying to do for almost 2 years and guess what; he hated this job. It was teaching 5 year olds and when he would get home he would just complain about it, this kinda ticked me off since he just gave us 2 or so years of having to struggle to pay bills for a job he hated more than his editing one. Ever since he started his new job i have noticed that i rarely see him when he had not had something to drink, at times like midday he would be drinking a beer and by the end of the night he would be getting really weird.
As of about 1 month ago our dog got ran over and 2 weeks ago my grandfather (on my dads side) died, this did not help his situation and i often see him with teary eyes, i feel really bad for him. Today i found out that he quit his job. He said that he might go and volunteer somewhere and possibly have a better time than at his old jobs. I feel really bad for him but then i look at my mum that is working all the time and i kinda get annoyed at him, he drinks everyday and this does not help at all, i wonder if he didn't spend so much time feeling sorry for himself he could get himself together and realize that a job is not supposed to be fun.
Am i right it thinking like this or am i just being selfish, any help would be appreciated.
PS: also any advise about what i can do to help me dad would also be nice
