Improving life

So I've realized how much I dislike who I am i guess you could say... I don't really even know who I actually am I guess. I really want to improve myself and my life. I'm on disability so I don't work, my disabilities keep me from being able to fully live and go outside honestly. I don't really know where to go from here other then knowing I want to change and become happier. Does anyone have any advice? I recently just started water colour painting I'm honestly terrible lol but I figured it would be a distraction. it's like all I do is watch Netflix and just waste away everyday... thank you for any help I really appreciate it
