In some cases it could be a case of self-fulfilling prophecy, that if you believe you are cursed, anything that goes wrong in life would be seen as causal, linked to it, whereas it could be just “coincidence”. Life happens whether you are cursed or not.
How many people have put hexes and binding spells on Donald Trump over the past decade? And yet, here we are. He looks like he’s doing well 
In terms of magick, it’s seen as a big no-no though. What you send out comes back to you threefold. So if your mother and friend had put hexes on you, they will have to pay the price and receive the energy of that hex three times as powerful.

Black tourmaline bracelets/pendants/amulets are also seen as protective, you could wear one to make you feel more safe and grounded.
Also cleansing your home with White Sage can dispel negative energies, turns out it’s even effective in clearing out a haunted house. I regularly sage my space after doing a spring clean, and it does genuinely feel lighter afterwards.

Also, look at the transits that have occurred over the past few years, since the “hex”. You may find its a slower moving outer planet up to no good.
Edit to add: you’ve had transit Pluto Aquarius square your natal Chiron Scorpio in 11th house (friends, groups) since around late 2022, early 2023. And still within orb as Pluto is retrograde.
Scorpio linked to occult, dark arts, also power struggles, dominance, and Chiron rules issues that are irreversible, cannot be healed. It could be your friends that are playing out the Chiron, holding power over you that you see as unresolvable.
The Pluto Aquarius is calling for transformation via detachment, completely breaking away from that social group, to find ones that are more healthy for you.
