Fellingssss

So I don’t know if it’s just me but every summer I get really really sad and my emotions are all over the place. I get sad randomly or angry. I don’t want to eat or be around people and I’ve lost friends over this. I usually don’t go on my phone because I’ll have my friends text me but I don’t have the energy to even answer them. My sister thinks it’s seasonal depression but i don’t know and this strange feeling I have the thing that won’t let me be happy bothers me. I can’t get ride of the ‘feeling’ and i can’t stay come completely happy how I want to. I’m used to keeping things in and staying happy because I’m a lot of people’s anchor and I’m supposed to be happy to care for them. But I can’t do this anymore and all I want is to be happy but I don’t know how.
