Body issue help **possible triggers

Looking for some genuine helpful tips / work outs not a slap stick "do some planks" which is all I get out of my siblings.

I'm always bullied about my weight, always have been and unfortunately always will be it feels, this has resulted in 2 years of bulimia, self harm, suicide, yoyo body weight and reclusiveness.

I dont hate being fat... I hate how I get treated when I'm fat.

I've been thin and fat, and honestly the only thing that affects me in either physical state is how others treat me, I actually quite like my large thighs and squishy arms, I like to joke that they're boxer speed punching bags and I genuinely don't feel bad about my body for what it is but when other people are brought into the equation its a whole different story.

I've had people be my friend when I was skinny and want nothing to do with me when I got fat, same with boys, even my own family showered me with compliments when I was at the peak of my bulimia yet the minute I put some weight on I had unprovoked "opinions" thrown at me about my weight... why? What's the need? Why do they feel like they have to say anything about it? My nan even has a bias towards it and trys to tell me it's because she cares about my health but honestly my health is my concern I'd rather her care more about loving me and just being supportive my weight doesnt have to come in to that support if it's something I'm not focused on.

I wasnt healthy when I was skinny, I was bulimic and mentally ill. I was miserable and didnt even try to hide it yet everyone preferred me that way? It blows my mind, theres just no need to comment on someones weight regardless because its relentless.... smokers dont even get as much unsolicited comments, not 1 person has ever come at me or made a sly remark about me smoking... but my weight is fair game?

Sorry I went on a rant, it just sucks 😖... I'm tired of the negativity and I'm trying SO hard not to resort to my old ways, I shouldn't do this for other people and I know that but they're making me miserable, I'm not allowed to just be left alone when I'm fat so I feel I need to change, it's not healthy, I shouldn't care but I'm at the end of my tether with it all 😢

Any workout tips, 10 minutes 5 times a day sort of advice not long work out routines I'd like something effective but gradual I'm not in a rush to do this and make myself unwell again
