I am tired.

I am 28 with a 3 year old. I've been a single mum since he was about 7/8 months. Ex partner turned really nasty and abusive to the point... my mental health collapsed. When to stay with my family but.. that was trash and toxic. They side with my ex ( I come from an abusive family that's just trash... I didn't really go home until... I needed to.. I would have died if not I needed respite... and sadly that's all I thought I had) Fast forward to now; My once okay relationship with my sister has been shit? Had to kick her out I'm at school working as a carer & going through court proceedings as I'm trying to be a mum I'm currently also going through an assessment for autism and things are starting to make sense and add up But I'm fucking tired I'm tired of being the one who has to have everything together, be the bigger person, and just let people do certain things coz oh they are young? Or they have stuff or whatever the fuck.... but I don't get this grace I'm tired of having to do everything by my fucking self and have people pick at it and undermine me. I'm just tired. This isn't where I saw my self and... I'm actually not sure wtf ? To do next or where we go from here... because I'm tired and I'm done and idk It all just seems so pointless I've been buying my little on gifts all month... each time I've gotten the chance and.... he turned and said " I'm sad I have no big gifts" and....... honestly I've done the best I can..... and I'm Just over everything.
